Heck yes! Everything in my current pc sux! The motherboard is plain DDR type, which is the oldest type. The new one is DDR2 type, which is kinda the best right now. DDR3 is the newest, but I haven't heard good things about compatibility and stuff.
I jump from a 2002 windows to a 2010 windows, which is great.
My video card is an ATI radeon 9600. In the GeForce series, the one that is kinda the same, is the Geforce ~4000. I'm gonna use the 8100, so guess how much ass kicking my 3D will have.
My processor jumps from 2.1GHz to 2.8GHz, which means the computer will run faster!
I get four times the RAM I already have, which means I can run heavier programs without running out of memory, AND I get 2.5 times the storage space I already have!
moar space for my p0rnZ
All in all, I'll be able to enjoy an ass-whopping PC!!!
