What do you expect to upgrade to? Your CPU is probably a P8400 at 2.26GHz. A T9400 or P9500 will cost well over $300 & a T9600 will cost well over $500. You'll get double the L2 cache but only a few 100MHz increase in clock speed. IMO, it's not worth it.
I want to make it faster may adding a 2nd internal HD (RAID 0) ? adding another GeForce ? can add the i with 1GB to my excisting card to get 1.5GB of VDDR3 or do I have to pair it to the same 512MB to get 1GB? I appreciate any and all feedback, I'm a newbie thanks guys! :-)
