I have only recently taken a interest in building my Own Computer and I have something in mind but I don't know if it is the best I can afford (budget being £900) .I am unsure what components to get . I already have a HD7870 TAHITI but I am currently bottlenecked by the rest of my system which is 6 years old .I would be using my computer for gaming and other general tasks .


The system build I have put together myself is
1. MSI MPOWER Z77
2. I5 3570k
3. HD7870 TAHITI (already owned)
4. 32GB of corsair 1600MHz RAM
5. Corsair cx 750 Psu (already owned)
6. 2Tb segate HDD
7. 128GB san disk SSD
8. H110 watercooling by corsair
9. Corsair vengeance C70 case
10. Windows 7 home premium

Which comes to a total of £853.39 (does not include things I already own)

Does anyone have suggestions on where I could improve my system but still keep it under £900 ?

Also how far would I able to overclock the I5 and maintain reasonable temperatures
