Hi all here are my specs: Gigabyte 3.4 ghz Pentium D Gigabyte S series Motherboard Maxtor 230 gb hdd ati x1300 pro pci express 600 watt pwr supply 1 gig kingston (2x512mb) I play counter strike 1.6 and counter strike source. 1.6 runs perfectly while i still get a drop in fps in source. Overall my computer is running great and i bought it only 2 weeks ago. I am able to get a deal on the Geforce 7900 gs for $150 Canadian. I have reviewed some of the specifications but i am not to knowledgeable with video cards. Would it be worth it to upgrade from the ati x1300 pro to the geforce 7900 gs? would it run that much better? what are the main differences? Any help would be appreciated thank you.
