What's a good gaming desktop?

Build one, or I could build one for you and I can sell it too you through ebay.

I would definitely look into having someone build one for you. Because a lot of these people that get online and try to build then sell you PC's way over price it. But I think that the guy John that posted on here might be able to build one for you and sell it to you for a decent price.

The part list above is the recommended parts for a good gaming system. Skip the SSD and find a cheaper HDD to save money. You need to select your own case & power supply but you can probably hit your budget.

Do not change the i5-4690K or the GTX-970 video card. This combo is the best bang for the buck right now if you want to game.
