How do these processors compare?

I am buying an imac, so if you do not like me already, feel free to leave because any aters will be ignored. I am deciding between a refurbished 2009 imac which has a 2.8 GHz quad core i7 processor and a new 2010 imac with a 2.8 GHz quad core i5 processor. How does the old i7 quad core compare with the new i5 quad core? Thanks, Tom

Update:

Also, please bear in mind that the refurbished model with the i7 will cost me £1399 as opposed to £1650 for a new model with the i5. Is the better graphics card really worth £250?

    They are very similar except as mentioned the i7 has hyperthreading. However, you might prefer the new i5 iMac because it has significantly better graphics. (ATI Radeon HD 5750 with 1 GB GDDR5 memory vs ATI Radeon HD 4850 with 512 MB of GDDR3).

    The i7 is better because it has Hyperthreading- it can run 2 instructions in each core, so it's almost like it has 8 cores.

    I think for the hyper threading for cores I'd go with the i7..
