Thanks for the replies.As for the direct comparison, that PC will be faster. The 9800 GT is a faster card.
If your happy to spend around $1K, you can build a system yourself that will be much faster.
If you want to do more research look for benchmarks for the 9600M GT and the 9800 GT, good way to compare.
I don't want to build a computer because I don't know how and I have bad, bad luck when screwing around with computers. I short circited my mobo as well as other parts of my last desktop. I had issues putting in ram in my MB and thought I burnt something there, ect.
So it is a better computer for gaming? thanks.
