I have 2 superclocked EVGA GTX 560Ti's in SLI and they are pretty great cards. Good build quality, no problems, overclocked both to 980MHz. But if I had ot to do over again I'd have a hard time turning down the MSI Hawks. They're the best GTX 560Ti's available right now IMO. The Gigabyte SOC version is pretty good too.
I've been looking at the different cards and it seems that there is no difference besides for the manufactures(warranties) Is there any major difference in cards besides the warranties or is it one of those "you get what you pay for" type things?
If you want more warranty then go for EVGA.If you want to tweak and overclock no one can stand in front of the MSI HAWK.But I advice you to get a Radeon 6950 2 GB instead of a 560ti.560ti is great but there is a difference that the BIOS of radeon 6950 can be flashed an you can get the performance of a Radeon 6970 which is much superior.Also 560 and 6950 fall in same price range.
