The PC gaming version of console wars. Nvidia vs ATI. Green Team and Red Team.
Which side are you on? Which brand (evga, asus, pny, diamond, xfx, sapphire, etc) do you prefer? What card do you own? Do you prefer multicard systems (SLi / Xfire) or single card rigs?
Also serve as discussion for future upgrades; dream purchases.
Many years ago I was hardcore ATI supporter. As of the last 5 or so years, I've been backing Nvidia. My first custom build had a 9600gt in it the week they came out, currently I have a GTX 260 core 216. These two cards have both been evga cards; the lifetime warranty and the step up program are great perks to buying evga products.
I'm looking to upgrade this weekend; currently thinking of going for the nvidia gtx 570; with the hopes of adding a second 570 later down the line (going to have to upgrade the psu when that comes). Also waffling with going ahead and going with a pair of gtx 460 1gb cards, which about equal in power the 480/570, but come to about $400 flat pre-tax, while the 570 goes for about $50 cheaper, and is single card, giving me the option of upgrading through sli later.
Speaking of upgrades, you can find a nice hierarchy chart of gpus courtesy of tomshardware. It suggests not going for an upgrade unless your target new card is three tiers higher, which is p sound advice imo. I also suggest looking into the related articles on that page: the best gpu for your money, the best gpus in XX - XX price range, etc.
