So in this summer or at the start of fall i want to upgrade my actual pc to a gaming one, and i was wondering what you think about it:

CPU: Intel Core i5-2500 3.3Ghz (my actual cpu is an i3 3220 3.3Ghz and i don't think is good enough for games from our days)
GPU: nVIDIA GeForce GTX590 3GB 2X384 bit (this card is actually A BEAST, wuat you think?)
RAM: 8GB ofc.
Power Suply: I don't know something with more than 500W+
Motherboard: i will use my actual board which is a GIGABYTE H61M-DS2H.

What you think about this configuration? Good for gaming in these days? How many years will this build resist? And best question: WILL THERE BE ANY BOTTLENECK?
