It's that time again.

It's faster, yes, but does the advantage justify that price and how long until it too won't suffice anymore?

Well I was kinda hoping someone here would be able to tell me that. As for overclocking; I'm a little nervy after watching a video of someone who overclocked his CPU so much it literally exploded. I don't really now if the cooling system I have is capable of taking the strain

Well anyway, my fears were realized though not to the extremes anticipated, rome 2 is working but only well when on medium graphics and when I stay away from getting close ups on the melee, now I come again in the vain hope of gaining advice on getting better results.
I suspect I can get my Q6600 to overclock to around 3 Gigahertz fine, but the suitableness of my Gpu (Nvidia GTX 560 ti) is a matter of some doubt. It's benchmarks on other websites dont exactly favour it and if it is too weak no amount of overclocking may help get around such a bottle neck. Way I see it there is two options I can persue, one is replace it with a meatier video card probably costing £3-400 or get a second GTX 560 ti for £100 and link them together, now I am somewat iffy about the second one as the internet has not been kind on reviews of my current motherboard (tp45 hp) and it's compatability with nvidia's SLI capability, yet I have yet to find a website that outright states it's not doable.

So my questions are:

1.Would replacing the GPU give me a worthwhile performance boost or is it fina and my CPU is the piece dragging it down?
2.Will my motherboard allow me to link up a second GTX 560 and would doing so give me enough of a performance boost to make not getting an entirely new GPU in the £400 range worthwhile?
3. If need a better GPU and linking two 560's is not viable what would be a good replacement?
