So I am looking to build a gaming computer capable of running games like GTA4 and Crysis on max settings. I have spent the past 5 hours researching components but I'm still a little lost. I looked at the hierarchy chart and narrowed it down to these cards:
GTX 275 - $225
4870 - $150
4850 - $105
I'm thinking about going with the 4850 just because it's half the price of the 275 but only 1 spot below on the chart. If it helps, the monitor I am planning on using is the Dell S2409W (1920*1080) or something similar in price.
Here are my questions:
1) Is there a major difference between them (or should I consider another card)?
2) What features / specs should I be looking for?
3) How will games run on max settings with these cards?
Well first off crysis at max settings requires an obscene amount of power, so much so that in the review of the 5870 the only 2 configurations capable of handling it were 2 5870s or 2 GTX 285s, and that was with no AA, settle for high settings and a 4890 should be plenty http://www.tomshardware.com/reviews/radeon-hd-5870,2422...
What power supply do you currently have and do you currently have a graphics card? You may have a cheap upgrade option available by using two cards. But a $105 4850 is likely a 512MB model which wont stand a chance a 1920x1200, the 4870 or 4890 are the best options.
2 4850's will actually perform slightly better, but you can generally only use a MIR once even if you bought 2 of the products so its slightly more expensive to get your graphics power that way and you need a crossfire capable board and a PSU with sufficient power.
