Hi guys, I'm currently having stutter issues with GTA 4. I recently put my 5870 and it stutters like mad on nearly any graphical setting! I never had this problem before with my 4870. My specs are i5 @ 4ghz, 8 gb ram, and I recently bought a new harddrive just to fix this problem because I thought it could be that on its way out
but as you can guess, theres no difference. Has anyone had the same prob? If so your help would be great
