Looking to upgrade an old OC bundle - need advice

I bought a OC bundled system in July 2010. Having checked my orders the system no longer exists on the main website but I think it is the following:

Radon Intel Core i5 760 2.8GHz @ 4.00GHz overclocked bundle (this includes the Motherboard which I think was an Asus P7P55D-E Intel P55 (Socket 1156) DDR3 Motherboard (unfortunately I'm not at home so can't check)
Asus ATI Radeon HD 5850 1024MB GDDR5 PCI-Express Graphics card
4GB RAM (as part of the bundle)

I'm looking at upgrading this system to:

New SSD

Nvidia GTX680

or

Nvidia GTX760

and possibly depending on how much I dare spend an additional:

an extra 4GBRAM

My question is will my i5 be able to run these GFX cards without bottlenecking? I don't really know enough about it but I don't want to go and pay for new Graphics cards if the mobo/CPU etc can't get it to work to its optimum.

please help anyone that can.
 
Old i5's (2000 series) can only run PCI-E 2.0, but it'll hardly be a bottleneck cos 3.0 isn't that much faster (except with multi-card setups).

4GHz CPU should be plenty for a while yet still.

Is it a quad or duo core CPU?

I'm running a GTX 660 at 2.0 and it's eating everything I can throw at it.
However if buying now, it may be worth stretching to a 670 or 760 for £200-ish.

760 would be the way forward or a nice 7950 with £150 of free games.

I 'think' it's a quad but I am going only on my order summary from my OC account as I am currently on my hols on a works laptop so I can't actually check. I was hoping to make an order and have my shiny new stuff ready to install when I get back :)

It's good to hear that you think that the potential for bottlenecking is very low -

@snips86x - I was originally thinking of a 7950 although I won't be playing anything other than one online game on this PC (that's why I made it in the first place) but I was researching and the 680 and 760 both beat it in benchmarking performance - the 760 ws given an excellent review and the 680 is still 100quid more to spend at the minute.
Thank you both so far for your responses!
 
That's great thank you - the GTX680 is still 100 pounds more expensive so it's really a matter of whether I go for the newer GTX760 that is cheaper but lower performance than the GTX680.

If you are looking at the 680, I would also consider the 770.
 
Hi went for the following:

KFA2 Geforce GTX 770 EX OC 2048MB GDDR5 PCI-Express Graphics Card

and a

Samsung 120GB SSD 840 SATA 6Gb/s

Not sure what I had to do with the link you sent as the items are no longer in my shopping cart and they have already been shipped!
 
Think I might need some help again....

I was looking again at the GTX770 that I have paid for and ordered and saw it needed both a six pin and 8 pin power plugs. In the midst of all my indecisiveness I thought I was ok with the two 6 pins. My PSU doesn't have it as far as I can tell (I must explain that I am not at home for another two weeks as I am on holiday so I can not physically see inside my PC, and I don't live in the UK so I have to import everything which takes time). From the description I have read I cannot see any mention of an 8-pin plug on the PSU which is a:

I was hoping that by the time I get home all my stuff will be waiting for me. Do I now need to order a new PSU or will this one work....

From what I remember from making my PC a couple of years ago I wonder was there some sort of adapter that came with the PSU or something.

Can anyone help me and/or suggest an alternative if I can't use my existing PSU?
 
Oh sorry to bother you all with this. After some more research it appears that the Card itself comes with the 6-pin to 8-pin adapter :)

However it does appear that the SSD that I ordered doesn't not come with 3.5 brackets. Without these is there another temporary way I can fix inside my minitower?

Replace that piece of crap psu. Seriously, it's absolute rubbish. The one that Hyburnate posted is vastly superior in every way. The psu is the single most important component in a pc and is not the thing to skimp on. Even OCUK's description sataes that it is for entry level systems.
