So quick one, I know people don´t like many posts on this subject:
I´m trying to find a "bottleneck" in my PC (i.e. weather I upgrade GPU or wait a few months and change the entire thing)
CPU: Intel Core i7 950
GPU: Radeon HD 6870 1GB
RAM: 12Gb (3 x 2Gb + 2x4Gb) all at 1600Mhz
MoBo: Asus P6X58D-E
PSU: CoolerMaster 750W (60A on 12V rail)
Until a year ago - 6 months ago I used to be able to run almost anything on max settings, but I´ve realized lately with some games (Hitman Absolution and a few others), the games offer me an "optimal detected settings" of medium in some cases... Something of note is the fact that I live in Argentina, hence components are almost twice as expensive and usually 6 months behind on component availability, so top of the line upgrades are not really an option. Considering I built this machine almost 3 years ago (lately I added the extra RAM, which is why the RAM configuration is kinda awkward) I have no idea if I should buy another Radeon 6870 to crossfire, go with a more powerful GPU like the GeF 660 or the Radeon 7970, or if upgrading the GPU is a moot point, because my CPU is dragging me down. I "kinda" want to futureproof myself for a comparable PS4 configuration (and the new XBOX), since I did that when the XBOX360 and PS3 came out, and it has lasted a big portion of this generation´s games.
Should I upgrade or wait another year or so and redo the entire system?
