Quick, what kind of RAM do you use in your computer, what is the max amount you can put in there, and how many slots do you have/can you fill???
Time's up. If you knew all of the answers off the top of your head in less than three seconds, it's time to put down the redbull, get off of your butt, walk to the nearest exit door, and go stand beneath the yellow sky orb for a while. Try not to think about the pixel ratio of the grass, or the depth of the street sounds you hear. It's called life. Welcome. Wait, you were subconsciously hitting a combination of the wasd keys while you were imagining doing that, weren't you?
For the rest of you, here is a nifty tool:
Crucial tells you EVERYTHING you need to know in order to upgrade your RAM. Crucial even has a tool that will scan your system if you don't know what kind of computer you have, or what current RAM you have installed.
They even have seem to have really good prices too. I picked up 2GB for my Dell this morning (That's a 200% upgrade since I only have 1GB currently). It was only $60. That's about $140 less than I was expecting (At Best Buy, from what I could find online, the same amount of RAM cost $171.98). I'm sure you could maybe get it cheaper from newegg.com, but last time I bought RAM from them, it was bad, and they would only give me an 85% refund, and made me pay for return shipping. This is about the fifth or sixth time I've used crucial, and I've been extremely satisfied every time, and they continue to impress me each time I go back.
Another nifty feature is that crucial uses FedEx to ship your stuff, for free. Then you get a tracking number and can sign up for e-mail updates so you can watch in eager anticipation and be notified the second your product gets one checkpoint closer to you, it's loving new owner and final destination. I don't really shop online... ever. So maybe this is just a normal thing, but it's good for me. I'm really really impatient, so I can't stand shopping online. When I want something, I drive to the store and get it. Who can wait 5-7 days to get that shiny new toy??? Not me (usually).
***Edit*** I ordered my RAM Wednesday morning at 7am, and I just got an e-mail today (Friday) letting me know it was waiting at home on my doorstep. Awesome. I didn't even pay the extra for the two day shipping either...
