Hi, im going to build a new pc for mainly gaming and i was wondering if i should over clock because i have no experience in doing it so i dont want to risk anything if it wouldnt make a real difference. also, if i should over clock, should i over clock my cpu/graphics card etc...
here is my system:
Computer Case: Sharkoon T9 Gaming Case (Red)
CPU: Intel i5 3570 - (4 x 3.4 GHZ) - Ivy Bridge
CPU Heatsink: Intel Heatsink & Fan
Memory: Corsair Vengeance 8GB XMS3 PC3-12800 1600MHz (2x4GB) (DDR3)
Graphics Card: NVIDIA GeForce GTX 670 - 2 GB
Motherboard: Gigabyte GA-Z77-D3H (Intel Z77) - VGA/DVI/HDMI
Sound Card: Motherboard Integrated HD Sound
Power Supply: Cooler Master 750W PSU - Low Noise
Hard Drive #1: 1 TB (1000 GB) SATA-II HDD 7200 RPM 32MB
Hard Drive #2: 60GB OCZ Agility 3 SSD SATA-III, Read 525MB/s, Write 475MB/s - Silent
Optical Drive #1: Samsung 24x DVD/CD Re-Writer/Reader - Black - (SATA)
Operating System #1: Microsoft Windows 7 Home Premium 64 BIT
(i realize the power supply is quite high for this rig but i am plaing to upgrade in the future so i dont need to get a new one if i require more power. also i know i will need a after market fan if i do overclock)
i have been told there is not much point overclock if your system can already handle the games so can this system handle intensive games such a BF3 easily without over clocking (60fps+).
finally, is it a good idea to buy the i5 3570k instead of the i5 3570 just in case i want to overclock in the future so i dont have to buy a need cpu (unless you can overclock the i5 3570)?
3570k > 3570 point blank. If you ever have the urge to overclock and you have the non-k, you'll kick yourself in the rear. If you don't have the urge and have the k-series, it can still run stock clock.
Some games will see a performance boost by overclocking the video card and processor but if your system provides results that are good enough for you then there isn't a point. But two years from now, you may have a different answer there.
So build it, run it and you decide.
As for the PSU, bigger the better I say. I have an 850w in my system and only 2 GTX550's and my 2600k that pull a lot of power. But if I want to drop two 670's into it; I have the ability to. So having that overhead is great as you don't have to replace a working part later on and just waste the money. It's like an investment for later upgrading.
