Hey all,

please give me your opinions witch way is to go in upgrading my dual CPU capable dell precision 650 workstation. For around $750 i can install two 2.8MHz Xeon CPUs 512kB L2 cash each or one 3.06MHz with 1MB L2 cash and put it in HT mode (all working on 533MHz FBS). Any ideas what would be better/faster for video rendering/processing?

i'm guessing with two CPUs it makes no sense to enable HT as XP can't handle 4 CPUs efficently.

thanks all.

P.S.
Guys, i didn't make myself clear. these xeons can work in Hyper-Threading mode (as two virtual CPUs). IMHO 3.06MHz in HT mode makes two virtual 3.06MHz giving total 2 x 3.06 = 6.12MHz with 1MB cash, and two real 2.8 MHz give 5.6MHz with 2 x 512 kB = 1MB cash. But still two real CPUs at 2.8 GHz might be faster than two virtual at 3.06MHz On other hand cash sizes are equal. Also 2.8 cost $340 each and 3.06 cost $760 So....should i go for $80 savings and two real CPUs or not? what would you do?
