then i went over to new Egg and prices some stuff out the following IMO is better product that will stay cutting edge for a while:
Keep XP, Vista bad (I tried it only last weekend) WoW does not have a big impact on the system, and your second would be capable of Bioshock at max settings, Crysis however will be playable at med seetings (some can be turned to high) but an E6850 is a lot for only an X1950.. my X2 4600+ EE doesn't run full load with my HIS X1950PRO (590/770) and I have played and beaten Crysis..the best deal is for a little more the HD3850 twice as powerful for barely the cost difference.. as mentioned before dial back your CPU for graphics performance (almost always true in gaming)
Edit: I forgot to mention, grab a different PSU, preferably not from newegg (they just cost more)... for PSU reference http://www.tomswiki.com/page/Tiered+PSU+Listings?t=anon
With the E2160 overclocked you can get some great performance. The $$ saved gets you a better v card like an 8800 GT 512MB and mobo thus a better system. But thats only if your comfortable with overclocking.
Otherwise at thevery least I would spend a bit less on CPU and a bit more on vcard. The best bang for your buck card wise is these days seems to be the 8800 GT. IMO
Good mobo, get the E6750. The E6850 is waaay overpriced for it's performance, which can easily be surpassed with an easy overclock of the DS3L. Take the extra $80 and get an HD 3870 or GT8800 video card.
