I'm planning to get a new 21.5in LED monitor to play games 1080p. Right now I have a 4 years old 17in envision LCD monitor with asus gts 250 and I can play starcraft 2 1280x1024 ultra quality + texture without any issue. But the problem is if I upgraded to a 21.5in, I will have issue playing it smoothly at 1920x1080. So I'm planning to get a new video card. I have about $350 to spend and I'm planning to get a 21.5in viewsonic LED LCD for $169.99 at office depot, so that leave me $180 for a graphic card. My power supply is a corsair cx400 with 30a on 12v rail (single 6 pin connector) so I believe the safest card I can get is the new radeon 6850. Galaxy also make a 768mb gtx 460 with a single 6 pin, but they are not available here in USA. So should I upgrade now or should I save up more money and rebuild my system in the future?
