I run a,
AMD FX-4100 4mb Cache
NVIDIA GeForce GT 610 (I think anything could be better then this)

But what I find amazing is it can run things like TF2 1280x720 all High, 8x __ Filtering, Anti Aliasing 8x MSAA.
All I would like is one that could run BF3 Low - Med 1280x720 with 30 - 40 FPS that does not need External Power supply.
My PSU is 500watt but does not have the 4/6 pin adapters, and I don't understand the Molex to 4/6 pin adapters.

I don't mind the budget as long as it is <£130 GBP I think thats like <$160'ish USD.

EDIT:
I know this is considered 'entry level' but I don't care.

AMD 7750, but you do need a half decent PSU.

the adapters are pretty easy to just plug in. Some gpus even come with the adapters. With prices dropping for amd cards you could get pretty decent card for that money.

I once bought a molex to PCIe adapter on ebay for $3 for an old PSU of mine. All you need is two spare molex cables if the problem is you have an old PSU. And even if it is low wattage, as low as 300w, you can still run something like the GTX 650 which is a mobile GPU in a desktop card. Anything under that and you might as well buy a new PSU.

Im sorry, I have a very bad PSU.
Here is a video showing it.

I'm making comments as they come to me while watching the vid.

Technically speaking "molex" is the name of the company who made/designed those plugs. Or so I've been told. All the plugs, from the 4pin aux plugs, to the ATX bundle are all "molex" plugs. But you are correct, that black one there is a molex plug. You would need two to power the adapter. You can undo the white molex in that other bundle, but you have a problem there. First, it seems that is powering a fan. Second, there seems to be about 3 of those plugged into each other. Probably more fans. The problem is video cards (or GPUs) like clean power. I doubt any card you buy is going to suck enough power for this to happen, but it's technically possible for the card to either draw so much the fans connected stop spinning causing heat issues, or the fans will use enough power that the GPU won't have enough for itself under a high power draw situation like gaming. I doubt a 7770 or GTX650 will cause this to happen, but I'm not sure what fans are plugged into there or where the limit is.

You are correct. You do unscrew those screws and then push that latch down. The card should slide right out.

Correct again. The yellow and black wires provide extra power to the CPU. Black wires are ground, while yellow wires in the computer provide 12V DC electricity. This allows for more power to come to the board and CPU then the 20 or 24PIN main ATX bundle allows/provides.

I checked out the PSU as best I could, but didn't see any info on it. My idea is honestly to not use any "500W" PSU that lacks a single PCIe 6pin plug. My last 500W PSU had two of them. My new 450W PSU has two 6+2pin plugs. If yours lacks even one, its not worth using anymore.

Unfortunately it is a Cheapo Branded one, and I know I should not cheap out on a PSU but I had no choice.
So would I be able to run a GPU that requires a Molex Plug to a 6 Pin Cable?

If so what is the most powerful, non power hungry GPU that I can run <£150 GBP?
If not what is the best budget one that only needs the power from the PCI slot?

I already answered your questions. You don't have enough free plugs to use an adapter, and your PSU is not a "real" 500W. Best bet is to buy a new PSU. Shouldn't be to much, I don't have any UK links.

I would almost wait until radeon and nvidia have their newer gpu line out I believe they will both offer low end gpu solutions that will require no pci-e power connectors

This one would be cheaper and still do the job.

If I were to get the PSU, I have never wired one up...
So what I would do is, unplug everything and note were they go, unscrew the PSU and just take it out.

Then screw the new one in and wire up anything that really fits?
Nothing is going to explode when I wire it up, right?

EDIT:
Could someone find me a cheap one on ebay? Preferably in the UK and suits my PC spec.

And with this, could a fit any GPU I would like under 260w?

More or less.

Considering how cheap that Dabs link was I'm not sure you could find a cheaper price. But here are the PCpricepicker links for the CX430 and the Antec green 380.
