Looking to replace RAM - Suggestions?

[j03h4gLund]

I have a slight studdering issue games such as Rift & Battlefield 3 and am replacing pieces of my build(See signature) to find the issue. I have tried everything else I can think of without replacing parts but to be honest its fine that I'm doing this because I'm building an HTPC with the extra parts. (Here's a link to my troubleshooting thread if you feel like I missed something)

I want the fastest quality RAM I can get. Here is the RAM I am looking at. Any suggestions?

G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2133 (PC3 17000) Desktop Memory Model F3-2133C9D-16GXH

Thanks in advance.

I run an I7-920 with a GTS 250 which does stutter when I try BF3 at higher res
but it runs fine at low settings

I see you did mention you tried lowest settings already
but I would still try replacing this first - just save receipt and return new card if doesn't work.
