I am going to purchase this customized PC soon. Intel Core i3 2120 3.30GHz Kingston 4GB DDR3 RAM HIS HD 6750 1GB DDR3 Cooler Master ELITE 370 Casing Will it be able to run Skyrim? If so, on what detail? keep in mind for 1280x1024 resolution. And How will it function on higher resolutions? Will it be able to run Space Marine? Same questions as above. Will it be able to run GTA4? Same questions as above. Thanks.
