I would try and get the latest gen Intel CPU as well as switching the SSD for something with better all-round performance. A great, cheap alternative would probably be the Crucial m4. Although much more a question of preference, I would switch the P8Z77V deluxe with Gigabyte's GA-Z77X-UD5H. It's got great performance and comes at a reduced price because it doesn't feature what I will simply refer to as "useless gimmicks and pointless features".
