Paul MaudDib posted:Unless you're literally running on a single PCIe 1.1 channel it's usually better than you would expect. And even with a 13% handicap a GTX 980 is enough for pretty much any 1080p use-case. Even 144hz and stuff like that. My motherboard has a feature where you can plug longer length cards into the x1 slots; something I've been wondering since I got it is: could I plug my 980TI into the PCIe 3.0 x1 slot and it would work? It just doesn't seem possible considering it is an eighth of the length of the x16 slots unless the length past the divider is just PCIe channels. I don't know how this stuff works really. And how much slower would it be than the x16, besides the seemingly obvious answer of 16 times?

CelestialScribe posted:Huh, okay. I don't really know much about AUS retailers (I'm Canadian) but judging that your dollar's even lower than ours, you're probably hosed unless you bump it up to $300 and spring for a cheap (probably blower) GTX 960. If it wasn't getting to be summer there I'd say start pushing more power into the card and crank the clocks until you have a few more bucks to drop.

And how much slower would it be than the x16, besides the seemingly obvious answer of 16 times? Yup, it would just work. (It might be really wobbly and hard to seat, though...) The divider is splitting off power delivery traces and the data traffic bits, which is why every PCIe slot has the first little part. It's not at all 16 times slower. Take a look at this image that was posted a ways up the thread:  Bandwidth has doubled with each PCIe generation, so a 1x 3.0 lane is going to be the same as 4x PCIe 1.1. So with the 980 in the image, you're still getting 75% of max performance.

I can do the R9-380 if I push my budget to $300. Would that be worth it? To be honest, I'm upgrading because my current card is hosed and needs to be replaced, and is out of warranty. So I guess it doesn't really matter what I go with?

Thirding the OK on the 380. You probably won't get much overclocking out of it but it's a nifty card for the price and can do tessellation fairly well for an AMD chip.

repiv posted:And as Paul MaudDib explained, bus bandwidth becomes less of a factor as resolution increases so at 4K you'd get 88% of max performance from that tiny slot. Yup, like I said the performance is much better than you'd expect. 1.1x4 to 3.0x16 is a 64x difference, but you're looking at a 12-25% difference depending on resolution, with higher resolutions providing better efficiency since draw calls make up less of the frame time vs rendering. The counterpoint is that it's an Amdahl's Law style situation. In computer science, this is a law that basically states that as you increase the level of parallel processing, the overall runtime is dominated by the parts of the program that cannot be parallelized. So if you have a program that is 75% parallel computation and 25% sequential and you apply 3 processors, you go from 0.75/3 + 0.25 = 50% runtime. If you apply 9 processors you go from 50% to 0.75/9 + .25 = 33% of the sequential runtime - 3x as many processors but only a 33% improvement in runtime. Here, as you apply more processing power, the time to transfer the game state plus the draw calls will come to dominate the processing time. Fortunately we're nowhere near the point where this becomes a problem yet. Using a flagship Pascal card to run 1080p will become increasingly inefficient though.

Edit: For that GTX 980, 4K PCIe 1.1 x4 vs 3 x16 is only 2 FPS lower? Now I'm thinking I could have just shoved this video card in my old pc's 2.0 x16 slot and I would have been just as happy. I thought you HAD to match a PCIe 3.0 card with a 3.0 slot or bad stuff happened. Ambaire fucked around with this message at 03:15 on Oct 7, 2015 |

Looks like others are having the same issue I had with my Titan Xes on their AMD cards and Freesync monitors: http://community.acer.com/t5/Predator-Discussions/XG270HU-freesync-monitor-flicker-and-graphical-artifacts-at-100/td-p/361331 Same symptoms, same troubleshooting, same results (artifacts stop when downclocked etc.) They theorize that GPU manufacturers aren't stress testing their cards at 1440p + 144hz. So it might not be that I got two defective cards in a row rather than that EVGA is shipping out cards that can't handle being run constantly at that level.

What? All the external GPU docks whether the old express card variety or the newer thunderbolt versions work with whatever GPU you plugged in then. They never came with a special card of their own.

My current desktop is pretty old, and I don't want to upgrade the motherboard and CPU if there's a decent laptop I can buy with a TB3 GPU dock. I have a baby on the way, and it's gonna take my office so I probably won't have room for a big rear end desktop any more.

Unless you're planning on doing your gaming on the couch or something, you still have to have some place to sit and use a mouse, and very small form factor desktops are all the rage right now. A laptop with dock + external GPU is going to be very much more expensive (Docks aren't cheap, they're generally at least a few hundred on top of the cost of the video card.) anyhow, and besides that, laptop graphics cards themselves have reached all the way up to the desktop 970 level just about. Nvidia is actually shoving real desktop 980s in new laptops, but, welllll, I hope you don't plan on ever using one of those away from a desk and power outlet.

The R9 370 basically is a Radeon 7850, and the R9 360 is SLOWER than your current card. The lower-mid-range is improving at a loving glacial pace, and the mid-range is hardly any better in terms of value. HalloKitty fucked around with this message at 13:48 on Oct 7, 2015 |

Any Canadian goons in here spy any good video card deals lately? I'm not a fan of the 100$ markup on top of exchange rate. They're really gouging us here. No particular card. Any reasonable/smart purchase between a 380 and a 980ti.

You don't really see deals for much at all on video cards unfortunately, maybe $10-$20 off at most. That said you can get this 380 pretty cheaply, only ~$30 more than a 380 costs in the US.

Nvidia has launched a new bundle, buy a 970 or up and get either the new Assassin's Creed or Rainbow Six. That translates into a 20 - 30 usd savings if you flip the code.
