Why would you prefer Nvidia? If you are on a budget deal, intel and Nvidia is not you best bet...and even then, Radeon GPUs like the R9 290x are often better than their Nvidia counterparts. But oh well.

Hey, don't tell me I got it wrong with the Radeon GPU. You give me a price cap, and usage, I give you performance.
If you want high FPS, you need good monitors. Start with 1 Asus VG248QE, then AFTER you SLI/CrossfireX, get the second one.
