Dell Optiplex 745 and a newer generation GPU

Hello guys. We are talking about a Dell Optiplex 745 Desktop - tech specs:

I am trying to use it for gaming so my first move was to buy an old almost free Nvidia 6200TC and put it in there as when I got the desktop it was with integrated GPU. With that old Nvidia I achieved a lot, I could run newer games like Aion although with a lot of lag.

Now I want to upgrade the GPU but I know there are a lot of characteristics to bear in mind.
I am trying to get the most of this cheap computer system to play new MMOs as better as I can and as cheaper as possible,balancing the two sides. I was looking into the GeForce GT 240 card - tech specs here:

But I don't know what to look for that would match the motherboard? I know the motherboard has a PCI-E 1.0 slot and the GPU is 2.0 but from what I read the loss in performance is not that much, and I'm sure it would be a lot better than the current Nvidia 6200TC but what would be the best card for that old motherboard, because I think it's not only up to the PCI-E slot?

For example I read that the slot for GPU is 64bit if I'm right and this GT 240 is that a big problem?

In the Optiplex specs under PCI-E x16 it says:
Data Bus 16 bi-directional differential lane pair (2.5Gbs per lane) 80Gbs total and the GT 240 says: Memory Bandwidth (GB/sec): 54.4 GB/sec but I don't know if I should be comparing these?

Thanks a lot in advance and ask if you need any more info. I'm a bit of a Nvidia fan BTW.

You can get GTX 650, HD7750 or HD7770. You have a pcie x16 1.0 slot, which has a maximum bandwidth of 80GBPS so you have to buy a card which has memory bandwidth of less than that.

Which CPU do u have in it? If its c2d, 7770 by AMD would be the absolute max u would need for that system, if its the old Pentium D, dont even bother...

Yea it's the c2d cpu 2,13ghz if i'm recalling right... that GTX 650 is a bit expensive for me....What about that GT 240 specifically, would it fit the system? Because I found it on a good price

What is your budget? Buying an old card is not wise and it is better to buy a new card why don't you go with 7770 $130 or HD 7850 $160

Yea ok then, AMD 7770, anything higher would be held back by the CPU.

Okay my budget is a lot lower than 100 and that's why i'm asking what do you guys think about the matching of Nvidia GT 240 with the motherboard....and cgner, as I said I prefer talking in nvidia cards :D 

I guess my question now is what characteristics I should be looking for to match with my PC except for the maximum bandwith and the pci-e slot rather than GPU suggestions ?

GT240 is an upgrade only next to.... I dont even know what lol

YOu can get this card for $115
Or $100
Or $140 if you want to have multiple monitors.
Or $130
Or $100

So for $100 you have to choose between a GTX 650 or a HD7770 GHz Edition. I'd say go with the amd card but here are a Comparision list
Rather than pcie slot and max bandwidth you should be looking for a card that will fit in your case and a powerful PSU that can support the card and also has the required power connectors.
