Hello
I just got a new gaming pc for about £430 from Ebay. I played several games such as gta iv, crysis 3 and minecraft on low setting. I noticed in gta iv i get about 20-30 fps on very low settings, crysis 3 was werse with 10-15 fps on very low settings aswell and I tried minecraft which is mostly runable on any normal pc but on mine i can run minecraft on normal settings (60-70 fps) but on high settings (20-25) which is quite playable. I used software such as game booster which made only a slight improvement in the fps. now the person who i bought this pc from has said it can run any game on high settings.
Pc Specs:
cpu: AMD FX 6300 6 Core processor OC @4.1 ghz
ram: 16gb DDR3 Dual channel 1600 MHz
gpu: XFX Amd HD Radeon 7750 2gb (low profile) 800MHz/667MHz
os: Windows 7 ultimate 64-bit (activated)

Is the problem the memory clock speed because my one is half of the one I should be getting.
Also I tried amd overdrive and tried to move the memory clock speed to the max which was 1000 MHz but every time I did this my screen froze and has a pink fuzzy screen and then my amd catalyst starts to crash and freeze my whole pc.
 


LOL
DDR = double data rate. The clock rate is actually half of the effective transfer rate

But even my core 2 duo and radeon 6670 can max out minecraft and hold 40 FPS. It still seems to be underperforming to me

how is your GPU usage in game?
