Yes I know it has "6ms GTG;12ms" but I'm not sure if that's a problem would that be a problem for upcoming games? I think my Sony has a 12ms response time and looks good to me. Would a TN monitor be better?
As for modding, it's Half Life 2 and it's what I do most - play around with Hammer.
It's a matter of personal preference also, because a little ghosting might not bother you much. If you could look around at some local shops you might find some to compare... I'm about to post a build here for you, but the lights are flickering and the wind is blowing. So, if it's not up in 15 mins it likely won't be tonight
By pure chance I was able to buy an XFX Radeon HD 5850 from Newegg so I'm ready to roll.
I think I'll go with the rest of the build as is, except getting the Cool Master HAF instead of the Antec. I googled around and found an article on modding the fan. It seems like it would be easy to swap out the red leds for blue. If not I can either live with red or cut the wires.
Is the cooler really needed whilst I'm not overclocking? I probably won't do that for a while.
