what gpu to upgrade to?

post #1 of 20
Thread Starter 
So i have had my 5770's for a while now and i am itching to upgrade. Not sure what to upgrade to. have been looking at going the single card route with a 6970 but is a single card really that much better?I also like the idea of 6870cf. I also thought about just picking up a 580 but then i can't add another in the future. What should i do?????? trying to stay under $600 or so but the cheaper the better

A single 6970 2GB (or a 1GB for that matter) will rape a pair of 5770s. A pair of 6870s will be about 10-20% faster than the 6970. A single GTX 580 will suffice for just about any game at 1080p. I'd say get a 6950/6970 2GB. A GTX 580 is about 15-20% faster but costs $150 more with 500MB less VRAM.

Single card setups have the most stability.

I've got a pair of 5770's too, and I'm also thinking about upgrading soon. Personally I'm going to stick with a single card, not necessarily because its better, but because single card is just more convenient. No CFX issues (I do a bunch of CAD stuff thats not really supportive of crossfire).

I'm gonna end up getting a 6950 or 6970, not sure which one though. 6990 is probably overkill imo

Get a GTX580. Its perhaps the best single GPU card out there.

So the 6970 would be a noticeable upgrade. Thats what i was wondering. I hope single card setups are more stable because i have tons of issues with crossfire not working right. Thats the main reason for me to upgrade.

Unless you plan on getting a higher resolution monitor or going multi monitor gaming(eyefinity or Nvidia surround)... a pair of 1 GB 6950s can be had for under 500...

Two of these are approx 450 AR...

If you plan on multi monitor gaming...Two of these are 510 AR

http://www.newegg.com/Product/Produc...82E16814125356

Either set up will destroy a single 580....

But if you insist on getting a single card setup... Either a 6970 2GB, or GTX580...In this scenario i would recommend the 580, if you were looking for the most power that is..

I don't think a 6970 is going to make for a very impressive upgrade from CF 5770s... In the research I have seen, 5770s scale reasonably well.

CF5770: 27.2GP/s|68GT/s|154GB/s|2720GFLOP
6970__: 28.2GP/2|85GT/s|176GB/s|2703GFLOP

The ability to do double precision floating point operations would be a nice bonus if you wanted to run particular distributed computing programs. At this resolution (single 1080P) I don't see a huge benefit from the higher memory bandwidth. The only substantial difference would be in texturing, which will vary from game to game.

Even with scaling losses on CF, I would never be able to justify parting with money for such a small upgrade... To say that the 6970 will force sexual intercourse on the unsuspecting DVI port of a CF5770 configuration is highly misleading.

1GB 6950s and 5870s are available in the $200-250 range right now. In my eyes, they are a far better value than the 6970 which is still $320-350. I don't see a need for 2GB VRAM for a single 1080P monitor. I guess if I absolutely had to do an upgrade right now and had up to $600 to blow, I would save ~$100-200 and just go with a new CF setup of 5870/6950s. Dollar for dollar that looks like the best deal to me right now. The resulting performance improvement would be roughly double compared to the CF5770s... I would personally still have a hard time with this upgrade, since I'm one to wait until the performance gain is going to be more like an order of magnitude.

What kind of issues are you having with crossfire? Im running a 5770 tri-fire and I don't have crossfire problems. I too am looking to upgrade but only because im running eyefinity. 5760x1080 is alot for 5770's Im going 6990 as soon as the gtx 590 makes the price drop
