Okay, with a 32 bit system, only 4gb memory total will be recognized- thats including RAM, GPU, anything else with mem.
So, for instance, if you bought the 9800 GX2- your computer would only recognize 3 GB of RAM. You might want to consider x64 edition.
As for the graphics card, the 8800 GT will work ok, but I would choose to SLI 2 8800GT's for MUCH MUCH better value with barely any difference in performance over the 9800 GX2.
In this benchmark, it shows 2 8800GT's running better than a 9800 GX2. It would also cost about $150-$200 less
