Hi, I'm currently looking at two options for a Mac to take to Uni (for CS): Mac Mini 2012 2.3GHz Quad-Core Intel Core i7 4GB 1600MHz DDR3 SDRAM - 2x2GB (will upgrade to 8GB myself) 1TB Fusion Drive Intel HD 4000 £790.80 (after education discount) and then a monitor: http://www.amazon.co.uk/LG-IPS234V-PN-AEK-inch-Screen-Monitor/dp/B008F7GW2K/ref=reg_hu-rd_add_1_dp iMac 21.5" 2.7GHz Quad-core Intel Core i5 8GB 1600MHz DDR3 SDRAM - 2x4GB 1TB Serial ATA Drive @ 5400 rpm NVIDIA GeForce GT 640M 512MB GDDR5 £967.20 (after education discount) and a £70 BTS card - will also probably sell the mouse+keyboard since I already have some. The questions I have is which is better value, and also what is the real-world performance difference GPU-wise between the two (for light games like Diablo 3 and Tekkit)? GeekBench says that the Mini is slightly stronger CPU-wise (due to the hyper-threading I presume), and also I can afford a Fusion drive in the Mini! The 21.5" iMac is pretty much at the end of my budget - and also the Mini has the advantage of being open-able. Thanks!
