Depends on budget and what you have for the rest of hardware. I myself work on a smaller budget so I would have made sure I have at least 4gb ram and a halfway decent GPU which set you back 100-150 for a budget I'd limit myself with for that CPU. And than spend a little bit of money on a quality budget board to OC on. As I remember seeing people being able to hit the 3.6ghz mark somewhat reliably back when this came out, getting more out it was alot more difficult though.
But it's a old CPU by todays standards and there are a lot better things out now which if you have the money I'd invest in something new. Than I would overclock that.
Just recently I had a locked HP mobo, and I bought a Biostar TA990FXE and it let my OC my anthlon ii x4 630 to 3.4ghz. So it worked out great for me and I am able to push off getting a new CPU for a while and save some money for a nice one instead of settling on my previous budget.
I already have a gtx 570, and ddr3 ram is dirt cheap.. i just need to find a good cheap motherboard
There are a lot of Motherboards in the market. I suggest a board with a Z68 chipset LGA 1155 socket, at least 2 PCIe slots for a video cards that you might want to do SLI or crossfireX in the future. enjoy the feature of a Z68 chipset like: Virtu Lucid(utilizing both of the iGPU built-in in the CPU i5 2500K and the discrete video card(you bought gtx 570) and Intel SRT (SSD caching). Good kuck to your PC building!
How? Can you explain to me why It is not good? Do you personally used Biostar MOBO in the past and have bad experience to it? Or you just saying it because you heard it to other people. Remember that all the PC motherboards that we are using right now are made in Taiwan, some people may have DOA boards some have not. So don't judge a MOBO by its name. I know that Biostar as a brand is not as popular as ASUS, AsRock, Gigabyte, MSI, EVGA and Intel. For your info this is the SPEC's of my PC Gaming RIG:
