BTW i am looking for that 7900 card I saw a WHILE ago on newegg.com... I see a lot of brands with a "7900GS" label, wheres an nVidia 7900 GS card?? Any links pls?
Had that card you are planning to buy. It was great (Doesnt work anymore due to human error). The only thing you can overclock 100% will be your video card which will only get you a couple more fps. If a software overclocking program like clockgen works for your chipset, you could overclock your cpu and ram. Since the ram and cpu run 1:1, the ram Dell uses is generally crap, and their cooling isnt the best, you wont get very far.
Lesson learned here, never buy a Dell if "getting the most out of your computer" is what you plan to do.
sell some crap on ebay to add money to you $100 and buy the radeon x1950 like he said above, it will rape the 7900gs. How old are you?You sound young, sell your sports cards, magic cards, whatever ya got lol. You would be amazed at what you could sell on ebay. I bet that if you advertised an old dirty pair of boxers on there,, some freak would buy them,, and bam, you got 10 bucks lol
