My old rig is on it's last legs as far as keeping up with current games and I'm looking to build a new system from the ground up. I'm currently running a Gateway GT5032 model, specs are: AMD Athlon X2 4200+ Dual Core CPU 2GB PNY Optima Ram DDR PC-3200 500W XCLIO PSU Gateway Motherboard (Very Restrictive) - (Foxconn variation) 250GB Western Digital HDD 7200 RPM Sapphire X1950 Pro 512MB Video Card PCIE I'm looking to upgrade to either a Core 2 Duo or if it's really worth it a Intel Quad Core CPU. Also, the video card I have in mind is a Radeon HD4870. So I guess, If you were building a system what would be some of the components that you would go with to get the most bang for your buck. Money is of course a factor, but by no means will I be going 'cheap' this time like I did last time by buying a prebuilt system. TIA, any questions feel free to ask and I'll be sure to answer as quickly as possible.
