PC bottleneck when re-drawing graphics...HELP!!!!

[JNMann]

I recently built a new PC, spec as below. Generally it runs really fast, but I often have to export graphics from CorelDraw, into Photoshop and then trace in CorelTrace before importing back into CorelDraw.
When I import back into CorelDraw the graphic can contain 10's thousands of items and when I ungroup them the PC often comes to a standstill. I know it's not stopped, it just seems to takes absolutely ages to ungroup.
Am I expecting too much from the system? Could my graphics card be the problem? I've tried playing with the scartch settings in Corel to no avail.
I'd appreciate any advice anyone can give me.
Many thanks in advance!

I'm guessing a bit here, but I wouldn't think the Graphics card was the problem. If Corel is Ungrouping 10s of thousands of items, I would imagine that comes down to 100s of thousands of calculations. More ram and a faster processor would be my bet to improve things, but there are some jobs that just take a helluva time!

I'm trying to keep an eye on the CPU and memory usage whilst it does the work, both seem OK. I'm wondering if I can devote more of each to the task in hand somehow.
I agree though, perhaps it just takes a long time to do some jobs!!!

Intel 3Ghz / AMD3000+ is considered a minimum spec for many graphics programs nowadays.
