rapt raid0 to 2 barra's

[GreenThu)v(b]

At the mo i have 2x 74gb western digital raptors in raid0

I want to sell them and buy 2x Seagate Barracuda 250gb 7200.10's


would i see much of a performance decrease?? this is my current hd tach score



all im looking for is performance. Capacity doesnt bother me as i only use my raid setup for windows and games.

game loading times, ingame smoothness and just general windows perpormance
