I am looking at upgrading an Asus M11AA-US001Q. The CPU looks fine however integrated an Integrated GPU just doesn't cut it. I was planning to upgrade the Psu to a corsair 430w and put in a gtx 750. The computer by itself is about $220 while upgrades should run about $130 after a newegg rebate. Is there something wrong with this idea, is there another way going about getting a cheap under $400 (with os) somewhat gaming pc? Also what are some good monitors 720p or 1080p under $50
