Finally, got time to play around with them. Let's see them first.
From the pci, Sparkle, Asus, and Leatek.
From the cards , we can easily see that only one different from the other two cards
is Asus. It's not made by reference design.
Let's also see the RAM IC:
SPAKLE=>Hynix 4(300/500)
ASUS=>Hynix 3.6(300/550)
Leadtek=>Hynix 3.6(300/550)
Testbed
K8 939 3000+ 0.09m,300x9=2.7g
MSI K8N Neo4 Platinum
G-Skill TCCD DDR600 256MBX2
SPAKLE.ASUS.Leadtek
PLEXTOR 712A
PSU CTW550W
SPAKLE default,300/500,4 pipelines
ASUS, default,300/550,8 pipelines mod
SPAKLE OC 566/666,4 pipelines
SPAKLE OC 550/660,8 pipelines mod
from the result we might understand that the mod for 8 pipelines all don't have
any problem doing benchmark with almost 1000 points difference.
I think 6200 is kinda decent price for budget card right now.
User might care is what IC(RAM) manugature used on the card.
