Around April I will be upgrading to an e8400, and using my old 7900 GS. Unfortunately, my old crap DDR2-533 RAM that I bought a couple of years ago won't work in my new mobo. (I will be building a separate computer off of my old rig with the old RAM though, so don't tell me how I can make the old RAM work in the new mobo ) I am on a really low budget, and upgrading to the e8400 is a huge stretch for me, so I am trying to decide weather to buy a 2x2GB set of RAM (http://www.newegg.com/Product/Product.aspx?Item=N82E16820231122) for $90 or a 2x1GB set of RAM (http://www.newegg.com/product/product.aspx?item=N82E16820231098) for $45. Could I expect very much extra FPS in games with more RAM? Or any faster converting/saving videos and audio, graphic rendering, etc. And general use in Ubuntu Studio 64-bit? I am aware of the 4.3GB total memory limit in 32 bit operating systems (I'm using XP Home for gaming). I am not an overclocker either, if that should mean anything for this decision. Thanks.
