x1950 pro vs 6600gt

Currently i have a asus p4v800d-x motherboard which supports both agp and pci-e x16 (in x4 mode).

My setup is;
mobo-p4v800d-x
graphics- 6600gt agp
processor- intel pentium 4 3.06ghz northwood (socket 478)
ram- 1.2gb

I was thinking about upgrading to a sapphire x1950 pro 512 mb pci-e version as this would later make the transition to pci-e x16 easier at a later date.

Would this be a worthwhile upgrade on a 6600gt, and would the x4 pci-e slot be a major limiting factor.

(I have around £150 so if you have any other better ideas please let me know)

Any help would be greatly appreciated.

whatever he said

if you want to check this site you can see what sorta performance boost you may get: http://www.tomshardware.co.uk/graphics/charts.html

That should be enough, but you would have to check how many amps it has on its 12v rails.

As far as the video, its a great choice, but you may also want to consider the 256Mb version because you wont see much of a performance difference between the two and you can save yourself some money for a future upgrade or new computer.

how many watts does it say on the label for the 12v together?

it does seem to me that you have an old type of 500w wich has alot of power on the 3,3v and 5v while you need the most on 12v nowadays...

okay you got the one i bought years ago cause i thought "hey look 500watt for £17"

a big big no....that psu is actually only 300 watts max. its not 500 watts. Its not a bad psu at the 300 watt range but its not good enough for the x1950 pro in any way.

So no that psu wont be enough. you need atleast 400 watts with around 22Amps or higher (safer to go higher).
