I'm looking at getting a GTX 770. I've seen two on Ebay:this one,and this one. Which one is better, and are there any other brands I should look at? And are the prices on them okay, or should I wait a bit. I don't really NEED a graphics card now, but would like to get one within the next 1-2 months @ $250-350. Also, will my i7-920 bottleneck this card at all?
The EVGA would be the better choice, their customer service can't be beat. The prices are very good, I'd consider buying from Newegg or Microcenter though as they are reputable distributors. Your CPU shouldn't bottleneck, but check around forums just to be sure.
Hope this helps!
