NEW COMPUTER REQUIREMENTS - for Autocad - HP Pro 3130 i7-870, 8 GB RAM & ATI V5800

Question: I have narrowed down our purchase of workstations for the AutoCad detailers and engineers.  These computers seem to be powerful and cost effective.  The form factor seems to be the variable that brings the price down.  We could get a z400 with Xeon processor, however they are priced well over a $1000 more than the Pro series for similar specs.  Over the years we have purchased HP xw series workstations, however we rarely upgraded them except for maxing out the ram to 3.5 GB (for XP 32-bit).

If possible, please let me know any solid advice that you have for these machines for AutoCad and AutoDesk Revit requirements.

Remove stock graphics card.  Install ATI FirePro V5800 other similar NVIDIA card.

Any suggestions for similarly priced workstations would be good also, but please advise on the above box also.

Thank you!
