Hey Guys,

So this is my pre-built http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01386890&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=ca&product=3692721&lang=en system I have had for about a year or so now.... What can I do to upgrade it so I can play the cool guy games for this year?

PS if that link i pasted in doesnt work it's a Compaq model Number SR5404F with windows vista 32bit

If it is running a Sempron processor, upgrading it to an Athlon 64 x2 4800+ (I found em for about $65 on google) would probably help a lot. A new vid card is a must, but make sure whatever you get will fit it your case, especially if it's micro ATX. These days vid cards can get downright monstrous, high(er)-end cards in particular. Slapping more memory in never hurts and it's cheap these days. If you're running XP then 2 gigs is probably ok.

Of course, depending on how much you have to spend it might make more sense just buying or building a whole new rig. 

Yea, you're probably right -- it looks like that's not PCI Express 2.0 x16 but just PCI Express x16, so you'll have to go with something like http://www.newegg.com/Product/Product.aspx?Item=N82E16814162022
