Need Help Choosing Video Card

Hey Guys,

I need help choosing a good video card for my computer. I need a video card for drafting and for gaming. I will be using AutoCad, SolidWorks and Pro-E on my computer. The type of games that I will be playing would be like HON, Neverwinter, and games in between. I just made the computer in one of my classes and I do not know to much about computers.

Here is what I used to make the computer.

Motherboard: Biostar N68S3B GeForce 7025 Motherboard - Micro ATX, NVIDIA MCP68S Chipset, 1333MHz DDR3, SATA 3.0 Gb/s, RAID, 6 Channels Audio, GeForce 7025, Fast Ethernet (B450-2423)

CPU: AMD ADX445WFK32GM Athlon II X3 445 Processor - Triple Core, 1.5MB L2 Cache, 3.10 GHz, Socket AM3, 95W, No Fan, OEM (A79-1445)

CPU Fan: Thermaltake CL-P0503 CPU Cooler - 70mm Fan, Rifle Bearing, Socket AM2, AM2+, AM3, 754, 939 (T925-1519)

Case: Diablotek CPA-0170 Diamond ATX Mid Tower Case - ATX, Micro ATX, 400W PSU, 2x Int 5.25" x 1x Ext 3.5", 2x Int 3.5", 2x Front USB Ports, Black (D15-1234)

Hard Drive: Seagate 500GB Serial ATA Hard Drive - 7200, 16MB, SATA-6G (TSD-500ST SY)

Ram (8 GB each): Corsair CMX4GX3M1A1333C9 XMS3 4GB DDR3 RAM - PC10666, 1333MHz, 4096MB (C13-1005)

DVD: Lite-On IHAS124-04 Internal DVD Writer - DVD+R 24X, DVD-R 24X, DVD+RW 8X, DVD-RW 6X, DVD+R DL 8X, SATA (OEM) (L12-1312 OEM)

I will most likely be getting D-Link DWA-556 Xtreme N PCI Express Desktop Adapter for wireless internet and this will take up the PCI-E2 slot. With this the video card can go on the PCI-E1 and take up one slot in the back of the case. Also has windows 8 right now but I may change it to windows 7 pretty soon.

Thanks
