Hi, I'm wondering what exactly I'll benefit from by choosing a DDR3 1333 CAS 7 RAM vs a CAS 9 one.
The computer will be used for playing diablo 3 (this game has very low requirements. recommended requirements are:
OS: Windows Vista®/Windows® 7 (Latest Service Packs) | Processor: Intel® Core 2 Duo 2.4 GHz or AMD AthlonTM 64 X2 5600+ 2.8 GHz | Memory: 2 GB RAM | Video: NVIDIA® GeForce® 260 or ATI Radeon™ HD 4870 or better), watching anime, and surfing internet.
These are the three RAMS I'm looking at. I need 1.5V or lower because I'm using sandybridge mobo. My CPU is Celeron G530 or Pentium G620. My video card is Radeon HD 6670 1GB 128-bit GDDR5.
Will benchmarks show an improvement? Yes. Will your human brain ever notice that difference in gaming applications? Nope!
Low latency numbers on DDR3 RAM, when it comes to gaming, are good for flexing benchmark numbers at your next LAN party. Anything at or below cas9, you're not going to notice the rapidly reducing gains.
Go with the cheap G.Skill unless the looks of a heat spreader are important to you. The heat abatement provided by a heat spreader on non-overclocked ram is negligible, providing you have anything resembling proper air flow.
