50k Need Heavy Auto Cad...
as for ur needs u said here and in Yahoo IM... this is what I feel would be best for u in my opinion...
19" CRT Non Wide Screen Display @ Rs. 8000/- + TAX
Q6600 @ Rs. 12500/- + TAX
ASUS P5K-C @ Rs. 8500/- + TAX
4 GB DDR-II 800 MHz @ Rs. 8000/- + TAX
250 GB SATA-II 16 MB Buffer @ Rs. 2600/- + TAX
XFX 8600 GT 256 MB GDDR3 @ Rs. 6700/- + TAX
Any Large Cabinet with Good Ventilation + PowerSafe / Zebronics / ColorSit 500 Watts @ Rs. 2200/- + TAX
APC 650 VA @ Rs. 2500/- + TAX
TAX Rs. 2040 at 4% VAT (Kolkata)
Total 53040
For auto Cad I think Q6600 is good...
U will need Non Wide screen Large high resolution display so think of that 19" CRT over any LCD i would say.... Not sure about the brand as in Kolkata, mainly dealers are pushing AOC / SAMSUNG for 19"...
Well I would say consider P5K-C over P5N32-e SLi
but try to get ATi 2600 sereais card over Nviodia 8600
8600 would worn just fine, but its better u put a ATi Card under that hood
see if u can find the ATi Counter part of nvidia 8600, price would be around 1k high for 8600 which i mentioned but u should go for that
