The new computer is going to be a desktop. He was going to spend around $600 for the box. I know I could build a better one, but I found one at Best Buy w/ decent specs.
i5 2310 w/ integrated graphics
8GB Ram
1TB HDD
...but, it's a Gateway for $599.
The prices of hard drives will make any build hard right now. Also, a graphics card update would be easy if it's low powered.
Which brings me to my next question...how would a HD6570 be versus a GTX 260m? I can't find any good comparisons.
