Config Help

I'm not sure yet when I will have the money to purchase the system but until then, I've decided to put my config of what I hope to be able to purchase. Whatever changes, improvements you can offer would be very much appreciated. Thank you.

Okay, so would it be smarter to do the boosting of the video cards, memory, and window tweaking later? It saves me money on not doing that stuff now I guess which is always a good thing.

okay, thanks.

Is getting duel 280's better than getting duel 260's for video cards? Is it all just a matter of cost and if you have the money to get it, or will you be getting allot more out of the 280's instead the 260's?

I see, okay. Cause I was just thinking that for certain games, if it really depends on the types of video cards you have, if I might not be able to run certain games, or does that have anything to do with processing speed?

The difference between the 260 core 216 and the 280 is like 1-3 fps in most games.

Plus if you overclock them even a little they'll surpass the 280s.
