What is the best web site for purchasing computer products such as hard drives and operating systems. I have tried DABS but is there a better one.

Hello, new to the forum but I have had great service from intensive-gaming.co.uk. Got a new graphics card from there and some memory, wasn't sure about what the max was my machine could take (thought it was 4GB) they helped and said that it was only worth putting 3GB in as the machine could take 4GB but would never use it. Was impressed with the help and the fact that they were honest about the memory even though they could have made more money out of me. Had some razer stuff there as well, going back for a lachesis mouse at some point!!
