If you're looking for a performance boost for an existing PC, Newegg.ca has a pretty decent deal on a solid state drive you might be interested in. Right now, you can pick up the OCZ Agility 3 2.5" 120GB SATA III MLC Internal Solid State Drive for $99.99 with $6.99 shipping after using the code CEMCNFJJ52 at the checkout and submitting a $30.00 rebate form. This is a pretty decent deal considering it's under the psychological $1.00 per GB threshold most are willing to pay and it'll add a significant improvement over an existing mechanical hard drive.
We all know what a pain mail-in-rebates rebates can be but, if you don't mind waiting, this is a deal worth considering.
The deal is live now and there's a limit of five per customer. Shipping, as mentioned above, is $6.99.
Thanks to pcdouble for letting us know about this one.
