[Solved] Striker extreme new ram

Hi, my ram (4gigs ocz) died awhile ago (like over a year ), and I've been using 2x1gb kingston 800mhz ram ( http://www.newegg.com/Product/Prod [...] -_-Product ).

My graphics card recently died on me(evga 8800 GTS 640) so I've decided to buy a 460gtx hawk, and I'm wondering if I should purchase new RAM as well. If I do buy new ram I'll probably want 4gigs. But, I would like to know if the ram I'm using is suitable (my computer runs slow at times, obviously it could be a number of things ..including the graphics card that just died ..but I feel like upgrading ram will help).

I have my eye on some G.Skill sticks, all 2x2gb DDR2:

$65 800mhz 5-5-5-15
http://www.newegg.com/Product/Prod [...] 6820231122

$80 800mhz 4-4-4-12
http://www.newegg.com/Product/Prod [...] 6820231209

$85 1066mhz 5-5-5-15
http://www.newegg.com/Product/Prod [...] 6820231246

ALTERNATIVELY, what if I just bought 2 more sticks of the kingston I'm using (to total 4gb) for $30, would that be acceptable or would I notice a performance increase by purchasing some G.Skill ram(or whatever 'gaming geared' ram)? J/w since I'm dishing out $180 for the hawk, I would like to keep costs down, assuming minimal/no performance loss.

Frankly, I'm a bit upset that ddr2 is still so expensive. I would like to know if the cost difference is justified between those sticks, also if you want to suggest any other ram, please do, G.Skill just seems like reliable ram.

I mainly use my pc for gaming. As of right now nothing is overclocked, but I do plan to OC my CPU, and I wouldn't mind OCing my ram if it's worth it.

Sorry for the wall of text, and THANK YOU for reading this and I appreciate any advice -- but please don't respond with simply "buy this", if you could try to answer my questions and perhaps give a reason why I should "buy this".

Considering you have 64 bit, I'd rather see you with the full 8gigs that the board will handle. However, money being a concern for now. I'd get the 444 Gskill for now, bookmark it, and pick up another set of those sticks if you plan on keeping the board for more than a couple of years.

That's fine. Good job.
I pulled up your board's QVL from the ASUS 680i page to make sure the voltage and timings were good, and they are.

Make sure you cover all of your bases when getting rebates...always!
Make photocopies of everything, or scan them into a file onto your HD - that's what I do - bookmark every page you go to because,
I have come to the conclusion that companies only send out the rebate if you inquire about it after their waiting period.
That is a good deal for DDR2 RAM these days.
