So I'm thinking of buying the MSI GeForce GTX 950 GAMING 2GB GDDR5 and I have the Intel Core i3 2100-3.1Ghz.Will it bottleneck this GPU? If yes, by how much performance and would it be better to buy the 750 Ti Gigabyte 2GB (speaking on the same CPU) I also habe a 400 Watt PSU so I guess that's good.
