I agree wit Hardwood pull the usb and find or by a long CatV cable to plugin directly test that out for a while then if need be dress the cable nicely to your comp. If that doesn't solve the issue, try another router/hub/switch/modem what ever it is. If thats not it then its probably not the network (PS You need at least 512k bandwidth for high end gaming, recommend 1meg++) also check your ping times all-around the internet.
And if thats all good then yea your video card/ windows x86 (can recognize 3.5g i believe)
Make sure that your 3300 on board video card is off, and that the ram is not being shared.
That is for right around 100 bones its as cheap as I would suggest you go, upgrade is ddr3 with 256-bit vs your 64-bit (still 512mb witch is ok), the stream processing unit though is 10 fold from 80 to 800 witch helps a TON.
This is around 150 bones, The step up to the 5700 series would be worth it! 4.8Gbps on 800 stream processing units will run most games at a pretty good res (not balls to the wall res)
I'd suggest trying to take to newegg, and tell them you'd like to trade that card in for the 5770 just my opinion.
