so recommended to wait till june for Haswell, but what would you recommend and from what i have seen is prob going to be around same price of the 3770k ($327 -£211 ish) is at the moment.. and would i be best waiting till i got the chip before choosing the motherboard or is there one you would reccomend picking up if i see it in sale
for the rest as in RAM 1866mhz or 1600mhz etc
and don't forget graphic card, AMD or Nivida..
Right now, a 3770K / 2700K, a decent Z77 motherboard (£100-£130), 8GB PC12800 RAM, a decent cooler (£30 will do), a good quality 550W PSU (£65-£70), a good case (£50-£100), a SSD for OS (128GB, £80), a hard drive (1TB), a good GPU (7950 / 7970 / GTX670) and that whole should be around £1000. Depending if you need a OS, display, ect... you may need to revise that (no SSD, cheaper motherboard / i5 CPU, limited to £250 HD7950...).
Haswell would be around that, if a little bit more expensive than the Ivy counterpart.
Recommendation, buy new if you can, £1000 will be enough for a good spec, and wait for Haswell to see if you can get better deals, or if Haswell delivers better value for money. AMD GPUs are better value price / performance, I wouldn't go below a GTX670 if you want to go NVIDIA. Since you're speaking in $$$, you will have more for your money since we always get buggered by the exchange rate / taxes.
