Which GPU and CPU? The Sonata will accept a std PSU.
I was thinking of installing a GeForce GTX 560, but perhaps something a little less expensive might go a long way. Do you have any ideas as to which GPU might work for me. I play games like Grand Theft Auto 4 and Modern Warfare. By the Way, I would also be installing a Gigabyte GA-970A-UD3 Motherboard, plus an AMD FX 6100 Processor.
