Hello Friends!
I am looking for a used laptop with Core i7 config. As new 2nd Gen i7 laptops are costing Rs.35,600 [ *www.ebay.in/itm/110953448311?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 ]
My budget varies between Rs.25k-Rs.30k. Lappies with GPU preferred. After a good offer, i will put my ASUS X53T (15.6", A6 2400M Quad Core, HD6720G2 GPU ) for sale *www.techenclave.com/images/smilies/dt880smile.png.
