You'll need a new graphics card for those games... Such as this GTX 460 Newegg.com - PNY XLR8 VCGGTX4601XPB-OC GeForce GTX 460 (Fermi) OC 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card, its 130 bucks after the mail in rebate.
Let me pick a cheaper motherboard for you. Do you want USB 3.0? What HDD do you have?
