This "Wintec Ampo" RAM looks pretty cheap, and it looks like you are not planning on overclocking or looking for ultimate performance. So you should just buy it.
We've used it in budget builds before, seems like decent stuff. May not OC the best or anything like that, but if you want cheap and functional, grab that.
I have 4 Gigs of Wintec Ampo 800 Mhz ram with the green heat spreaders and they work great. would recomend to anyone on a budget although they seem to perform just fine under stress.
