Wow, even with the I5 and the -8GB RAM? and I need that sort of hard drive size for gaming and media work I do.
Yes, for gaming you barely need 4GB of RAM but people buy 8GB kits because they are very cheap and the i7 is only good for extremely heavy video editing or photoshoping, in games they both perform exactly the same
take a look at this
As you can see, even in apps that properly use the extra virtual core of the i7 created by hyper threading it barely beats the i5
You might miss understood this image... the i7 beats the i5 by a large margin in SYNTHETIC benchmarks ONLY, those benchmarks are extremely optimized to use the extra virtual cores and measure only their bandwidth, theoretically this improves performance but in the practice it reduces it in applications that do not use the extra cores (games) and even if you use an aplication that makes proper use of the extra cores the performance difference is not going to be 33 or 52% like that image shows, a 20% at most.
