Neither, i would drop the 1TB drive to 500GB for 6GB of ram, change the GTX275 for a 4890 to save some so you can get a stronger PSU, a GTX275 is really pushing it with an EA500.
For 1000 i would go for an AMD build with a 4890, 4GB of low latency ram, and a PSU that supports future expansion.
500w is kinda pushin a 275... corsair 650w is $80 after MIR which is only $10 more than the earthwatts
I don't trust any company with HDD other than western digital or samsung...
Take a look at the Samsung spinpoint f3 or the 640gb caviar black. People told me the 640gb will have better performance than the 1tb caviar black because of the # of platters
thanks for replies
yeah, i was thinking corsair 650 but i heard in one of these forums, that someone was running 2 gtx260 with ea500.
and about HDD, its just my opinion but, i have used samsung, WD and Hitachi, and Seagate
but i like Hitachi the best,
i had doa WD(but new one works fine), samsung dead, seagate makes strange scratching noise when it starts, but works, making me worry that it will break soon..
anyways thanks
