2560x1440 120hz graphics card questions

post #1 of 6
Thread Starter 
So I just sold my gtx 570 because I upgraded to one of the new korean monitors (qnix qx2710) which is beautiful I might add. I was pretty sold on finding a cheap gtx 770, but everyone seems to be saying 7970's. I have 300, 350 maybe to buy a new card. Whats the general consensus? I do alot of gaming, no particular genre.

Maybe one of these?

Thanks yall.

I think if you're really into game modding with high res texture packs and all of that extra stuff that really eats up VRAM, I would go with a 7970. There's also price to consider, as the 7970 comes in at around $300 compared to around $400 for the 770. Unless you want to go with something that has PhysX, I would really consider the 7970 over the 770.

Find two used HD 7950s on something like Ebay or OCN's marketplace. They should be going for around ~$150-200 a piece. You won't be seeing the performance you want at 1440p 120Hz with only a single card unless you want to start turning quite a bit of settings down. 1440p is already incredibly taxing on current generation GPUs. And trying to run at 1440p makes it even worse.

the problem with 2x 7950's is a lot of my games i play don't support CF, Final Fantasy XIV MMO that just went into Open Beta for one, yet it supports SLI.

Had this problem with a lot of games. Cap Profiles are limited to only certain games. SLI not so much.

Kinaethetic is correct. 1440p is very demanding on gpu side. Even at 60Hz, you need 2 top gpus at this moment if you run all the games comfortably at the highest settings. If you are willing to reduce graphic settings, one top gpu might be fine. However if you would like to utilize fully 1440p at 120Hz, you need to wait for the gpus of the future based on 20nm technology or further. At this moment you could get one gtx780 to run games with reduced graphic settings for very demanding games. If you are willing to wait for HD9970 which is supposed to be released this October, this might be a good choice as well (Nobody knows the real specs right now). In the future you could get another either gtx780 or HD9970 to set up two configurations. As you said, I am far more comfortable with SLI than crossfire even now. ATI 13.8 driver is a stop gap for the older cards as an afterthought. ATI might implement hardware for frame time issues in HD9000 series as Nvidia does. Since one card is eventually not enough for 1440p, you need to think about the reliability of multi-gpu configuration. In this sense I wouldn't get HD7950/70 unless your main point is cost/fps ratio (I wouldn't say cost/performance ratio since performance means many things). If you get HD7950/70 at the moment, it will be a stop gap until gpus based on 20nm technology appear probably next year. Even with 20nm gpus, I suspect that you will need two or more top gpus to run games comfortably at 1440p/120Hz.

OP stick to a single HD 7970. Sapphire HD 7970 OC (1 ghz) gets my vote. unlocked voltage and good cooler. overclock it to 1150 and even at 1440p you can max any game like Crysis 3 provided you turn off MSAA.
