Well, awhile ago I was looking for a cheap gaming computer for under $400, and there was on deal I missed out on from ibuypower, and there was nothing else around except for the acer I bought for $380 (Acer Aspire X1200) AMD 4850e 2.5 ghz/4GB ram/ Integrated GeForce 8200. Forgot what motherboard but its either a Nvidia 630i or 780i, eitherway it has the Hybrid SLi setup. I don't know much about Hybrid SLi. When I got the computer it won't play games for crap..cod4 is like a strobe light, so hopefully a new graphics card will fire this thing up, what cards can i get that are useable with the hybrid SLi setup? and my power supply, whatever it may be I cant find the specs on it. anyone know anything about this?
