im tired of not being able to play richard with my friends. (that was entirely for humor, don't take that intentionally.) i'm on a tight budget of 300 dollars. i could barely milk out 200 for christmas.
If playing with your friends is worth $100-$200 worth of hardware, then go for it. I would definitely recommend an i3-4130 to start though, just tell your parents you'll pay them back or something at xmas if they loan you another $50
I'm now rolling with an i5-4690K, I've noticed massive decreases in game loading times over my old FX-4350. Feels good to have finally made the jump to Intel, up next is the jump from ATI to Nvidia as soon as I get the money for a GTX 780 (or 880 depending on whether or not it's out and how much it costs when I have the money).
Nice. Did you OC yet?
Keep in mind, nvidia is not better than amd or vice versa. In this specific case, I would definitely recommend the 290 over the 780 because it offers comparable performance for like $100 less, and it has more vram so if you want to crossfire in the future for 4k you'll have a much better time
