I am about to order my ram and was stuck on which of these two to choose: crucial ballistic tracer ddr2 8500 1066 and patriot extreme performance 6400 ddr2 800.

Now I know the crucial is the better ram without doubt but its also about 80$ more expensive. I dont mind to pay that if I will see a big performance increase but if the differnce will be very minor then I would rather put that into a better GPU. So how much of a difefrnce will I see.

Also how is the gskill ddr2 6400 800. Itsw priced just a tad over the patriot.

I will be running a
Gigabyte p35 ddr2 board
e6750 cpu
and may overclock a little but nothing crazy.

Thank you for any advice.
 


So how much of a difefrnce will I see.

PC6400 800mhz = 6.4 GB/sec. data transfer rate

PC8500 1066 mhz. = 8.5 GB/sec. data transfer rate.

So 8.5 GB/sec over 6.4 GB/sec is 32% faster...but how will that affect my total system performance taking into account I will be running a e6750 cpu. Is the e6750 fast enough to take advantage of the faster ram? When ever i see cpu benchmarks for the 6750 its always with ddr800...will I only see a difference when overclocking?
 
High performance PC6400 is capable of running at 1066 mhz. if properly overclocked in the right (capable) system. You have not mentioned your system specs. Think of an older system you may have had. Of course RAM running at 400 mhz (PC 3200 3.2 GB/sec. transfer) is faster tahn 266 mhz. (PC2100 2.1GB/sec transfer speed). I'm just trying to give you something to compare the RAM you are buying to.

Thank you mrmez...I think I understand, basically if I'm not planning to OC past 3.2Ghz(which I dont think I will) the faster ram will be wasted on my system.

@ badge: my system specs are gigabyte p35 ddr2, e6750, and a 2900xt pro.
 


Smart choice. 3.2 GHz is already a lot, and if you try to get even more it's likely to bring no additional benefit. The hard disks will hold the system back. Also, for a moderate overclock you can spend much less on the CPU cooler, maybe even just use the stock cooler.

You could probably OC to 3.2 on the faster RAM and use faster timings... but on an Intel system that wouldn't really give you much of a boost. You're probably better off getting a faster graphics card since even a stock E6750 should be able to push a very hefty GPU.

Also, what kind of pricing are you finding for the PC6400?
