Ok I got a dell I570 300w psu(gonna place a 600w psu inside) dell 04gjjt motherboard with 1333mhz ddr3 ram (gonna max it to 8gigs ddr3 1333mhz) Win 7 64bit oem , athlon x2 250 regor clocked at 3.0ghz. I wanna instill a ok graphic card to max out like diablo3 left for dead 2 and guild wars 2 at resolution of 1600x900 with 60mhz refresh rate. Would the bottleneck be noticeable or no?
i think your bottleneck will be your processor by far its very weak. upgrade to at least an x4. i do not think your x2 will be able to widthstand anything more than medium
