If you're on a budget, I recommend the i5 4670k or if you want to save a bit more money, an i5 3570k. It's still pretty powerful, but won't kill your budget. You can stick with your R9 295 for now, or you can get a GTX 750(ti) or a 760.
If you're gonna get the 3570k: http://www.newegg.com/Product/Product.aspx?Item=N82E16813157304&cm_re=lga_1155_motherboard-_-13-157-304-_-Product

Before you get this stuff, did you modify and tweak your config file?
