Proximon :
Just realize that the only real performance difference is the processor. The difference between a Q9550 and an I7 920 is not large, and almost non-existent if it's the Q9650.
lol...now you have me confused....so....I'm sorry to say, more questions...
Does this mean that I will have almost identical system performance if I just replace the Q9550 with a Q9650?
If so...what is the advantage of the more expensive setup? Which is more likely to be reliable over time?
I have shown the configs I am considering below; the main price differences are Motherboard and Memory. Will the shift from 6GB of DDR3-1600 to 4GB of DDR2-800 really make only a small difference?
I also notice that you changed from an ASUS 4870 to a Sapphire 4870 ... is that because it works better with the GB motherboard? Or just because it's cheaper?
I have kept some things constant in each configuration. These are:
2x
WD 1TB Disks - just want a little more (mirrored) space
CM HAF (seems like a very nice box with plenty of space)
Arctic Cooling (it's only $6 more)
Sony DVD(IDE, but should I go for SATA?)
by varying other options, I have 3 contenders:
1. ($2,786) Proxi's original:
Asus Radeon HD4870
G.Skill DDR3 PC3-12800
I7 920
CM V8
ASUS P6T Deluxe
Antec Signature 850W
2. ($2,406) Modified version of Proxi's cheaper option (taking elements from expensive), (*) marks changes:
Asus Radeon HD4870*
G.Skill 4GB DDR2-800
Q9650*
CM V8*
Gigabyte UD3P
Antec Signature 850W* (only $60 more for what seems to be a very safe bet)
3. ($2,216) Proxi's original cheaper version:
Saphire 4870
G.Skill 4GB DDR2-800
Q9550
Xigmatek HDT-S1283
Gigabyte UD3P
Antec Signature 650W
