Hi,
I need a PCI-E graphics card, for under £130($256)

And i was WOUNDER what was the best one

I'm getting a new motherboard (Nforce 780i)

and that one doesn't support my CURRENT Graphics card

thankshttp://www.amazon.co.uk/s/ref=sr_nr_p_36_pr?keywords=9600GT+&rs=560798&rh=n%3A560798%2Ck%3A9600GT+&low-price=0.00&high-price=130&x=0&y=0

I found these, but I don't get what makes one £100 and another £130, if there all the same make

also some of them say, Memory Type:DDR3

but my board supports DDR2 or is that just for ram They're not the same make, there is actually quite a few different brands in your link. The thing most of them have in common is that they use the same GPU. But that doesn't necessarily make them identical.
Take a look at the technicals specs for these two for example.

The second one have a higher core and memory clock than the first one. Whether the slight increase in clock speed is actually worth the extra money is a whole nother question though.

What RAM your board supports only matters when buying RAM. Graphics cards CONTROL their own RAM so MOBO support is not a factor.
Thanks Deerpark

You've been very helpful

I'll go with the cheaper one for now.
just an added note, its never worth purchasing a factory overclocked video card. you can overclock it at home for free.
