Before you tell me I should have built a custom-built PC, I know I should have, but then I went ahead with a pre-built one, knowing nothing about PCs. Anyway, I am soon planning to upgrade it. My current PC is an HP Pavilion 500-368na, the specs are 8GB DDR3 RAM, an i7 4790s and a very bad (possible bottleneck) Nvidia geforce gt 705, anyway, for my upgrade, I am going to get a very good budget card, or so I have heard, a EVGA GTX 750 ti 2 GB GDDR5 (the single fan version) and because I am not very familiar with the term bottleneck, will this be a bottleneck? So, after upgraded, I will have an i7 4790s, 8GB DDR3 RAM, and an EVGA GTX 750 2GB GDDR5.
