I have two questions that you could answer and clarify for me please:
Firstly would a Radeon 5670 1gb be bottlenecked by a core 2 duo E6400 2.2ghz ( might try to software overclock) mobo wont me change fsb
and secondly would a 5670 work on a 300 watt psu?
And lastly infact how noticable would would the change be from a Radeon HD 4650 to a Radeon HD 5670.
Will buy it today if these questions are answerd for me
Thanks.

It depends on what resolution are you gaming at. The lower the resolution the greater the bottleneck.

Depends on the PSU. If the PSU is of a good brand it will suffice, but a good 400W PSU will be more concern free.

The 4650 is 10-20% slower than the 4670 so you can make a comparison by using this review:

Get it to at least 2.6ghz, but otherwise, you'll be fine. The card doesn't use much power at all comparatively.

Its just a generic PSU that came with the computer, 300watts

IF it has more than (or equal to) 16A on the 12-volt rail you're fine.

Generics are usually sh^t plane and simple except for some OEM units from Dell and HP. I would replace the psu if you are using a card that requires supplemental power like a 9800gt or a 5770 as an example. In your case it has to be a high quality unit to be safe but if it is a junk generic then I would expect issues to show up down the road.
