I got the 6600 version of that graphics card, and I must say its great, so I won't hesitate to recommend it. I take it the RAM is PC3200 DDR?
Everything else looks great. One thing though. Get a Samsung Spinpoint Info here on Samsung's site
, some of which is wrong. That hard drive should format to around 230GB from 250GB. It's SATA 2, so it can go at 300mbps, rather than 150mbps like the Seagate Barracuda.
Here at Newegg you can get 200GB for $94, compared to the 7200.8 http://www.newegg.com/Product/Produc...82E16822148066
for $106, so your 7200.7 should be around the same price.
I bought a Barracuda, and I would upgrade to SATA 2 if my board could take it. In fact, I bought the Barracuda you are thinking of getting, and its good, if a bit noisy at times, and the Spinpoint is very quiet, in one review it said "Like a bat out of hell with a mute switch"
