I need some advice on the best card that will be able to occasionally play video games but mostly be used for Photoshop CS4 (i.e.-GPU use). The set-up would be a Dell XPS 420, a Dell 30" 3008WFP Monitor, 4GB of RAM and a Quad Code 2.56GHz. Oh and I also want to be able to run a Dell 2408 24" monitor with the 30008WFP. Thanks!
If you want to play games at 2560x1600 then I would recommend a card based on what kind of games you are playing:
For Cs4, any mid-high range will do fine
-For games like Call of duty and normal non-intensive games then I think a GTX275 or GTX280 would be fine.
-However if you play really graphically intensive video-games and want them on high settings like Company of Heroes, crysis, bioshock etc then I recommend you get either a GTX285 or a GTX295 or you can buy two cheaper cards like 2x GTX260s or 2x GTX275s, because that resolution is really really high, its far higher then 1080p so you are going to need something "beefy and juicy" to power that.
At 2560x1600 you really won't be able to skimp on a cheap graphics card. Plan on at least a 260 preferably a 275. If you go to sli, you will certainly need a bigger PSU but for any single card your power supply is sufficient (487x2 etc counting them as dual).
Anyway 2010 is going to be an orgasmic year for pc gaming so plan on being good for at least a year.
