Hi there, I just registered, saw your post and have to reply -- I hope it isn't too late! Please do not buy the 8200 graphics card!! It's a very crappy card. In actual fact it isn't a card, as the name says:
"Integrated NVIDIA GeForce 8200 graphics" Integrated means it's just one of the chips in your motherboard.
When buying a graphics card, if it is Nvidia never buy anything unless the second number is 6 or higher. (The first number is the generation, the second number is the power of the card, how suitable for gaming it is). Hence a 7800 is much much better than an 8200 or 8400.

So, the fact that Acer is promoting that pc with the 8200 "for lush images" and all that crap means nothing. It's just an integrated chip, now call that chip intel, or nvidia... maybe the nvidia is slightly slightly better but still far far away from a proper gaming card.

If you decide to buy the Acer, make sure it has a PCI-E slot inside and, depending on your budget, buy nothing less than an 8600GT. If you can get a 9600GT or 8800GT - they run spore smooth and well, and will be fine for other more demanding games too.
