Laptop for CAD/gaming under $900?

I'm looking into buying a laptop for college that would be able to run Autocad/Solidworks and also a few games... I'm looking to get the biggest bang for my buck so I thought I would ask the community. So far I have been thinking about these:

#1 Acer Aspire V3-771G-9697 Notebook Intel Core i7 2670QM Quad Core (2.20GHz) 17.3" 8GB Memory 1TB HDD 5400rpm DVD Super Multi NVIDIA GeForce GT 640M 2gb For $879.99 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

#2 HP ENVY 17T-3000 Notebook i5-2450M Dual Core (2.5GHZ) 17.3" 1080P 8GB 750GB HDD 7200rpm BLU-RAY ATI HD7690MXT 1gb for $876.46 on Ebay http://www.ebay.com/itm/360476196186?ssPageName=STRK:ME...

Would either of these two be suitable for the tasks I'm looking to do or are there better laptops out there for under $900 that would work better? Thanks in advance for any advice
