Need help with ram this time

O.k., I got the PSU handled, I haven't bought one yet, but I got enough info to make my decision.
So I've narrowed it down to these (I'm looking for DDR2 1066 4gb (2x 2gb) my Mobo cannot run DDR3 or I would get it):
Choice One ----- OCZ Platinum 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model OCZ2P10664GK
Choice Two ----- OCZ Reaper HPC 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model OCZ2RPR10664GK
I have a $100 budget on ram!
I mainly chose these because they had fairly good reviews, but they also had the mail in rebate (I'm trying to save as much as I can!)

 

Either one work. I'm not a big fan of OCZ, but to be honest RAM is RAM. As long as its compatible with your motherboard it will serve its purpose.

 

Thanks, you helped me a whole lot!

 

Make sure the voltage requirements match. The last thing you want is to fry your mobo.

 

I'm planning on getting this PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817339025, unless I can find a better bang for my buck, will that work with 2.0-2.1V?

 

The voltage requirement is between the motherboard and your RAM chips.
