Hey, i have a pretty bad computer.. but for some reason its holding up 4 accounts even in BG"s and arenas.
But i need a little more.. unpff.. i want to be able to have full control with no small hickups in the lag..
i know my computer is crap.. but im looking for what upgrades i can make.. with a buget
So atm.. i have 4GB of DRR2 ram..

CPU- I want to upgrade this.. but im not sure what upgrade will be compatible.. how do i know?

I am looking at
Intel® Core™ I7-920 Processor (2.66 GHz)
Intel Q6600 @ 2.4GHz
Core™ 2 Quad processor Q9550

the price on these are about the same.. but what one is better? for running 4 accounts.. in pvp.. thanks!

Also, 4gb is all my computer can handle..

Questions-
  1. What preformance upgrade do u get with a new videocard? is there less lag? or does it make it look nicer (and does making it look nicer slow down ur computer more)
  2. Which one of the CPU's is compatible with DRR2, and the rest of my computer...
  3. does upgrading to 64bit help! thanks!
