Buy overclocked or build myself?

[liam_abrown]

To cut an extremely long story short I need a new CPU as I am capturing HD and it has my CPU at 70%-100% within 5 seconds!

 

With my mobo I am not going to get the power I need (Gigabyte M61PME-S2P) so I am looking at going for Intel i5 or i7.

 

This has been recommended to me *OVERCLOCKED* Intel Core i5 750 2.66Ghz @ 4.00GHz / Gigabyte GA-P55-UD5 Intel P55 Motherboard / Corsair XMS3 4GB (2x2GB) PC3-12800C9 1600MHz DDR3 Bundle [] Overclocked Bundles Intel Core i5 added all the parts up and it seems you pay roughly £25 for the over clocking pre-set.

 

After browsing through forums that setup has been slated and people are saying they can build an i7 with 6gb ram for roughly the same amount (£500 ish). Well I am not a complete tech wiz but I understand the i7 is great for HD rendering which is my primary need!

 

So my question is can anyone please answer my call and point me in the right direction to building a better PC.

 

I will put the mobo, CPU and Ram into my current build which is:

 

Antech gaming case

ATI Radeon 512MB 4850 GDDR3 PCI-E

Seagate barracuda 500GB 7200.12 (I might set-up Raid 0 if I need to record uncompressed)

Corsair VX 450W power supply

 

Items which shall be replaced:

 

Gigabyte M61PME-S2P

Kingston hyper X 4GB DDR2 800MHz ram

AMD Athlon II dual core 245 - 2.9GHz

 

Please let me know what my best options are, take into account I do not know how to over clock properly hence why this pack OC'd from 2.66GHz to 4GHz looked good to me.
