Graphics Upgrade..

Well that sucks, another reason not to get an OEM PC, only thing you can do is a new mobo.

Sucks Big time, indeed.
Didn't you know the difference between G630 & G630T before buying that?
Anyways, 2 things need to be replaced:
1. Mobo
2. PSU (Get at least 450 W Corsair/Antec/Seasonic).

And, if you have the budget, upgrade that CPU also. Get a non-T Pentium G2120/i3 3220 at least to prevent CPU Bottleneck.

what about this Mobo: http://www.amazon.co.uk/Gigabyte-GA-H61M-S2PV-SKT-1155-... and this PSU: http://www.amazon.co.uk/500-WATT-ATX-POWER-SUPPLY/dp/71... Thanksfor the help  

You made a triple post... the mobo will do but that psu...just don't...really why buy something crappy as the older psu and it doesn't have a pcie 6 pin connector.

You need a decent psu : http://www.amazon.co.uk/Antec-VP450P-450W-Power-Supply/...

or http://www.amazon.co.uk/Corsair-CMPSU-430CXV2UK-Builder...

The PSU is despite common belief, the main component. It is more important than your mobo. A bad PSU means your computer could go up in flames. Get a Corsair or Antec ONLY!

What about this PSU: http://www.amazon.co.uk/Corsair-CMPSU-430CXV2UK-Builder... ?

Yes, that's the one i recommended, it will do.

No it won't work. You GPU requires at least a 500W power supply.
that is 430.

Are you trolling ? it wont reach even 300w full load...and i mean the whole system

scroll down on specs.. minimum psu wattage requirement 500 watts...

all GPU's have a min wattage requirement even if they don't use close.

Oh common that is a recommendation only, it is very subjective...

See this :

The most important is this : +12V@32A of the corsair vs crappy 500w with 18A, it means that the corsair have 384 watts, the 6850 only requires 150w maximum.

Like i said it will do, no problems whatsoever.

True, my bad; but extra never hurts in case he wants to CF in future.

Crossfire a 6850 is a bad idea anyway.

yeah if he could get his eyes off amd and get sli nvidia gtx 550ti's that would be sick.


so go with whatever djangoringo said, im being an idiot today lolol

Thanks for all the help guys, I bought a poor PC in order to upgrade so it's kinda a first build  

much cheaper to build from scratch though, on black friday i got a top of line i7-3770k with radeon 7870 2gb and all other parts, including os, mouse, keyboard, speakers, and monitor for only 750 bucks  

I'm probably being really stupid, but i'm English. What is Black Friday?

the day after thanksgiving in the usa, everything goes like 30-40% off, sometimes even 50-60%. basically everything is dirt cheap.

Sounds pretty cool...  

Why is it that although the OP gave UK websites you still think they're an American?
