Trying to decide on RAM--at a loss

[Turkeychase]

Building my first computer. E8500 on a P5Q Pro, Vista Home Premium 64, Antec 300 case. Looking to get 4 gigs of RAM for a good price ($100 or under). This is what I've looked at so far:

OCZ Reaper HPC Edition 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Retail
http://www.newegg.com/Product/Product.aspx?Item=N82E16820227267
$80, before a $35 MIR

G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL4D-4GBPI - Retail
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231192
$90

G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL4D-4GBPK - Retail
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231148
$85

Keeping the motherboard and case size in mind, which RAM do you recommend? By all means suggest another brand if you think it's a better option than any of those three--those were just what I've found so far.

Get this Mushkin:

$68 after MIR. Unlike the ones you listed, it will operate at stock at the JEDEC standard 1.8v.

Don't the worse timings kind of outweigh that benefit? I mean, won't I just be overclocking it up to 4-4-4-12 anyway?
