I am now noticing my 7800GTX cannot run full settings on even older games with the new monitor (1900x1200) never mind the new ones with all high settings. I can get an old used 2nd card 7800GTX for SLI but that seems sort of silly for old tech. What should I do? HD4870 ?, GTX260? For a 24" monitor what a good upgrade from a 7800GTX single card? I got a silverstone 640 watt zeus PSU so I should have enough power.
