Hi, all. Would love some help figuring out how to upgrade my current gaming rig. The specs are: Motherboard: Gygabyte P55A-UD5 CPU: Intel i5 750 @ 2.67 GHz (4 CPUs) RAM: 4GB DDR3 @ ~1300 frequency GPU: Sapphire Dual-X R9 280 3GB PSU: Don't remember, but it's from a really good brand, although at lower capacity than what would be recommended for this rig from other manufacturers. Never had a problem with it, though. Anyway, this rig had been good enough to run almost every one of the latest triple-A titles at full graphics at 1080p without a problem, though the Witcher 3 is proving to be way too much for it to handle and I'm afraid the next upcoming titles I want to play will probably not run very well, either. Already tried all kinds of tweak guides, different graphics settings, overclocking the GPU and it still performs poorly. Performance monitoring showed my four cores were running at maximum for this game, so I tried my hand at CPU overclocking too, but botched that miserably as the guides I read for similar setups resulted in my PC becoming unable to power up at all, and the Gygabyte Easy Tune tool simply does not install on my machine for some reason. I realize the RAM is relatively low (even lower than the minimum requirements for the game), but I'm not sure if that's what's bottlenecking me the most, or if it's the weak CPU. I'm not a complete newbie to PC hardware, but my knowledge is limited on certain topics, like whether my motherboard would still be compatible with current gen CPUs. I don't particularly fancy having to buy both a new CPU and a new motherboard. If possible I'd like to upgrade the CPU with something relatively low-budget, but I have no idea what kind of products I should be looking for. Would appreciate any insights on the matter, so I can spend my money wisely. Thanks in advance.
