Okay, lets face it. My system isn't amazing, and it's starting to show its age in games. However I am faced with a bit of a problem. The motherboard has pretty much no further expandability 
I've been looking around a bit, and this is the closest I could find to what I'm looking for.
YOUR BASKET
1 x Intel Core i5-3570K 3.40GHz (Ivybridge) Socket LGA1155 Processor (77W) - Retail £179.99
1 x ASRock Z77 Pro4 Intel Z77 (Socket 1155) DDR3 Motherboard £97.99
Total : £288.78 (includes shipping : £9.00).

But as you can see it is way overbudget, and to be honest I'm not sure my current CPU/Mobo would fetch much. Also, the motherboard has an 8pin CPU power, my PSU only has a 4pin. Guessing this would cause problems?
