It will be a work station rig. I had 6 presentations this semester and had to do alot of research and I really ran out of ram every time. I ran out fast. I don't doubt that even if I had 1GB I am sure I still would have ran out. For me right now the PCU is importent but more importent is having alot of ram.
For instance at one time I would open say 15 .pdf's, run image scanning software, run a chemical modeling program, open numerous IE6's, photoshop etc........
the modeling software took 15 minutes for its iterations while I could not shut odwn the other progs also. Just for this project I added another monitor to my rad9500 DD. This is getting crazy. I really needed HT or a dual CPU system and alot more ram this semester. I even considered running dual systems with two keyboards and the bit networked together.
