I am looking to upgrade my computer's components without actually buying new components (aka I want to overclock) and I don't know (too) much about the process so I was looking for tips.
The GPU was pretty straightforward, I moved some sliders in Catalyst Control Center until i got my Radeon HD5770 GPU clocked at 960 MHz and memory clocked at 1355 MHz. Scored 1866 in FurMark benchmark and the stress test pushed the GPU to a max temp of 80 C. Idles at 43-45 C. Don't think I can do much more there.
For the CPU, I know pretty much nothing about overclocking so I'm planning on downloading an overclocking utility (specifically Gigabyte's EasyTune 6: mobo is Gigabyte GA-P55-USB3). I'll just be doing a similar thing to my GPU in that it'll just be some sliders to move until i can max them out with the system stable.
My CPU cores (quad core i5-750 lynnfield) idle at ~28-30 C, and at load with prime95 they run at ~53-56 C. I have not cleaned the dust out my computer in a year (yeah I know I'm behind schedule) and I haven't reapplied the thermal paste since I built the computer two years ago. I still have the tube with the paste and there's plenty left. My case (Antec 900) is very open and my fans are mostly on medium because I can't stand the sound of them on high (one of them is stuck on high because I cut the wire but that's a different story).
My main questions are
1) is it worth it? (will my cpu bottleneck my gpu or vice-versa)
2) Is it safe? (dunno if I should be pushing my cpu too hard with the temps they currently get to)
and 3)Any tips? I know my way around the BIOS and i can change settings there, I just don't want to change them myself because I've never overclocked and don't exactly know what to change them to.
