intel/nvidia system for £800ish?

[neutrons]

Hi, first post here. I was just about to order a pre built system when I thought, come on it's about time I stop being such a wuss and try building something from scratch. I don't know too much about it but I'm pretty sure I can manage.

I do 3d animation so I need a decent cuda compatible card, which is only nvidia as far as I'm aware and I'd prefer an intel cpu.
I already have an ssd and some spare ram so 4gb should be fine. I don't need an optical drive either.
For the case I'd prefer something as plain as possible, no leds or anything to look a bit more professional when I'm in work, and if it's not going to add too much to the cost, I'd like to have the option of adding a second graphics card later when i've got more money.
I have about £7-800 although i could maybe go a bit more for a good reason.

One question though, I'm not confident enough to try overclocking it myself, am i right that the only way to get that already set up is to buy one of the bundles? would I be better off doing that perhaps?

thanks

I have to admit I'm not entirely sure what SLI means, I mean I get that it's a way of linking two gpus, but like, what would be the alternative? To be completely honest I don't really know if it's a stupid thing to be asking for anyway, I just thought the idea of having more than one graphics card sounded pretty nifty :/

as for the ram, I'll have to check that when i get home.

well at the moment there are a couple of c4d plugins i use which rely on it (turbulencefd mostly), and I'm about to start learning nuke as well.

although saying that, I guess I could do without it if it's going to add to the cost significantly
