That's right guys, DDR3 is starting to drop in price rapidly. No way of knowing how low it will go but a month ago it was a real struggle to get 4GB for less than £100.
Please note two things about this module.
1. It is a single 4GB stick, most modern PCs will perform better with two matched sticks (i.e. 2x2GB) but obviously the same applies to two 4GB sticks. If I only had 2 memory slots and wanted 4GB or if I was looking to buy 8GB then this would be ideal. If you have 4 memory slots and are looking for 4GB then you would be better buying a matched pair of 2GB sticks.
2. This RAM is 1333Mhz only. In real world performance the difference between this and 1600Mhz RAM is negligable. Where it can help though is if you are looking to extreme overclock your CPU when the faster RAM is great benefit.
