Nah not really.. My station eats about 280W when loaded (measured) and thats : pc + lcd + headphones amp + speaker amp + printer idle. EAX enviremental audio. Not many games make PROPER use of it. Developers just add it so it gives you the effect of a metal pipe when youre in one. Proper usage is to emulate the real sound behaviour for the player to use sound as a wallhack. I dont think Ive ever seen a game other than R6:Raven Shield that used EAX in such way. You could basicly know the exact position of enemy near you and you were able to supress footstep sounds with explosives and shooting. EAX gave that precision and the ability to filter a sneaking enemy inside multiple sounds. Im not sure dev's really care nowdays and dont even buy it from Creative and use their own 'echo' system which is actually good because EAX really worked completly diffrent on every card. About the computer I would really do everything in my power to wait a bit more for i7 - It is new gen and is just a few days/weeks away.
