Thanks for those responses! That helps a lot. I think I like the AMD setup better for what I need and cost wise.
No problem. imp! I imagined a low power gaming build would do as you requested. As mentioned before though, when you get the chance, buy a cheap HSF fan (around $20) so you can OC that Phenom to use its other 2 unlocked cores for better performance. Also, price wise, that build is great for a stable budget. 550 Ti by EVGA can play most modern games on some very nice settings. Once more, happy upgrade!
