justanoldgamer: OK
I've got a Core 2 Quad 2.5 Ghz 64 bits
8 GB of ram
GEFORCE GTX 650 1GB (The most I could afford to replace an ATI Radeon 4650 1GB that went bye bye)
So I'm a bit below on the CPU but I have no clue of the graphic card. Is there a site where they sort graphic card by performance?
PokerCrow: I've always found TomsHardware is a terrific reference point for purchasing graphic cards. Not only they recommend the best bang for your buck in different budget tiers (June review is
here), they also provide a hierarchy chart to compare cards from different generations (
here), which is more or less what you ask.
Second TomsHardware - been around forever and still great pointers. Also, don't worry about a new GPU yet. I posted it in another Witcher thread, but I'm "due" for a new GPU myself - however I can still play all the stuff I want to play, as I want to play it. In a year time when W3 is released, I'll be able to get that much better a card or figure out what new drivers are performing the best, letting that guide my choice.
Plus, no sense in shelling out for 3,100 teraflops of wing-dang-doodles, only to learn in a year that developers were able to optimize for having 8 quibit cores instead of WDD! Now your card is Wingdangdoodle heavy but only handles 5 cores (note: my terms are made up and NOT tech specs you should be looking for ;))
