Upgrades for an HP M8400F with $400

[Sniper-Fox]

Sup!

I have $400-500 to spend on my pc upgrades. I want to upgrade my vid card hella badly but I'm a bit worried about bottlenecking. I know for sure the PSU needs to be upgraded. What would you recommend to upgrade for my PC? I game on a 22" 1680x1050 res Monitor and would like to get pretty decent FPS (60+) in the games I play now; World at War, L4D, CoD4-Upcoming : L4D2, Bad Company 2, CoD6 MW2, and Assassin's Creed 2. One thing I'm concerned about is the PCI-E Slot in the Mobo, it covers the SATA ports if i get a GTX 260 so I'm here to ask you for recommendations.

My Main concerns: PSU, GPU, Mobo ///CPU (Least, just can't oc with OEM Mobo)


Right Now i see this as a great deal::http://www.newegg.com/Product/Product.aspx?Item=N82E16814127429

I'd probably just get a new power supply (Corsair 550w or equivalent)

Your choice of the GTX260 216 or a HD4870

and a couple of 90 degree SATA cable that will still fit under the graphic card.

Keep your old stuff, when you decide to build or buy a new system, reinstall old parts and sell the old system then move the new parts to your new build.
