£600-700 ($1k) gaming build request

Edit: Neglected a couple of mentions that I have now included, sorry for the kerfuffle

Hi there, building a new computer for the first time in 4-5 years or so! I could really do with advice as I am very much out of touch (SATA was a big surprise for me when I last built something).

Approximate Purchase Date: 2 weeks - 1 month or so (moving to a new property, housewarming gift to myself)

Budget Range: £600-700 (about $1000)

System Usage from Most to Least Important: Gaming, watching movies (may be buying a projector down the line)

Parts Not Required: Two Asus VE247H monitors, keyboard, mouse, speakers (I would happily upgrade to surround sound if possible). Essentially I have two hard drives I can use as well, so if less the cost of a new hard drive can get something better, go for it!
Old computer
Sapphire ATi Radeon HD 2400 PRO 256MB
MSI P35 NEO2-FR Socket 775 Mobo
Arctic Cooling Freezer 7 PRO
2 Arianet 1GB PC2-6400
Intel Pentium Dual Core E2180 2.0GHz (Retail 775)
160GB Samsung Spinpoint SATA2 8MB
not sure on the power supply, but I assume everything here is redundant now anyway

Preferred Website(s) for Parts: Not bothered, but clearly I am best off from uk sites, like aria.co.uk

Country: (e.g.: India) United Kingdon: London, England

Parts Preferences: A friend of mine is strongly advising I get an Ivy Bridge when it is released, so it would seem that the most logical thing to do is make sure the build is compatible to upgrading to that processor. I would like to make use of Eyefinity in League of Legends, as I understand this may require specifically amd radeon? I believe this puts me in contradictory hardware requirements though. I am not sure

Overclocking: Maybe, I prefer not as it is less hassle, but I know these things can be set to specific profiles for ease of use, so whatever

SLI or Crossfire: Maybe, I have no idea; I seem to be able to play video in one monitor and play games in the other without too much choppiness, but if it is a consideration for this then yes

Monitor Resolution: currently using two 24" 16:9 1920x1080

Additional Comments

As mentioned, this is largely a gift to myself for the new house. I'd like to get back into gaming seriously rather than playing League of Legends and TF2 on lowest possible settings, and we'll be using it as our media device in the living room. Some time down the line I hope to grab a projector, and I'm told I should be looking at Ivy Bridge, but clearly I am entirely out of the loop regarding computers. Luckily I am good at jigsaws.

Here you go:

Scan is a good UK website, so you can either go through them or put the build together on the site of your preference.

The motherboard is S1155, which is what Ivybridge will be when it arrives. However, although Ivy will be an improvement over Sandy, you're not really going to lose out by going Sandy now...it's still a fine CPU. The motherboard doesn't have the most comprehensive overclocking suite of tools, but should be find for your needs. You can shave some money off of that build by replacing the chassis to taste.

I realise I should probably add in that there is a feature I have been shown called eyefinity, which I would like to make use of in my gaming; does this require specific hardware? Thanks for input so far~

Well, bugger.

I take it both cards in the case of a dual SLi would need to be equally as powerful given they are operating independently, rather than say two weaker cards working in tandem?

Edit: Blimey, just found out how to set my Sapphire ATi Radeon HD 2400 to use both monitors and stretch resolution across both and play with both monitors... didn't realise it was that simple

So would it make sense to buy one of these now, and another down the line, or is there more appropriate options for such endeavours?

Yeah I only use 2 monitors; so 560Ti is the place to be then?

Thanks to all again for all the input =3
