So i'm building a new computer.
It will have QX9650, ASUS P5Q, OCZ DDR1066 4GB sticks and of course the all mighty HD 4870.
My problem is i can't decide if the 1GB version is so much better than the 512MB version.
In my country the price differences are about 85$

does the 1GB version worth it?

thanks :)

Depends on what resoultion you game at, if you have a 23 inch or larger display then it might be worth it.

I think 85$ is too much for the difference.

I suggest you get a Q9550 instead of QX9650 and use the savings to get two HD 4870 512MB and to upgrade the MB to P5E Deluxe X48 to avoid Crossfire bottlenecks. Get a 750W or better PSU. This way you'll have a much better gaming machine for less money. The Q9550 is already way overkill for games, so the QX9650 won't really add any value for the price difference, even if you overclock it like crazy.

What resolution are you playing at?


About the build itself, I wouldnt waste my money on an extreme edition CPU unless you are trying to break a overclocking world record. Just buy the Q9650 instead. It will save you about $500!!!

Spend the saved money on a better motherboard, a nicer screen maybe? Another 4870? :D

Q9650, P45, 4870 X2, corsair HX620...

even if u play at 1920 you'll never have any problems.

OK, Sorry for not mentioning it before.
but i get the QX9650 in the price of Q9300 :p 
Don't ask me how.

My screen is HITACHI 32' LCD with resolution 1366X768 (NATIVE) but some games don't support it so i run them on 1920X1080.

Wow, can I have a QX9650 at that price too? :) 

Excellent price for that PC Power & Cooling, only $110. I got one of those for almost $200 last year. There's also the Corsair 750TX, $100. The main difference is that the PC P&C blows the air to the back rather than vertically, which is smart IMO. Either would be excellent.

A P45 motherboard + HD 4870X2 would be faster than an X48 + two HD 4870 512MB cards at 1920x1080. It should be very similar to X48 + two HD 4870 1GB. You are playing at a high resolution and the additional RAM matters.

Oops, what do you mean "in my country"? If you're not in the USA forget all those nice sales at newegg. They won't even ship to me and I live just an hour away from the USA border. Are you in Canada by any chance?

No, I'm in Israel... :] lol
well the pcpower&cooling 750W is about 190$ here, so i thought about the Thermaltake Toughpower 650W which is Crossfire certified and costs 170$

I'm not really planing on crossfire anyway...

I don't understand. You get both the CPU and PSU for extremely low prices but the difference between 1G and 512M costs you 85$ !!! You can buy a good card with that.

colegade, again, I'm paying for the QX9650 75% discount from it's original price, so no, i don't prefer the Q9450 which actually costs more :D 

Nils, i can afford the price, but i thought i would spent it on other components like 750GB HD instead of 500.
That's why I'm asking if the price difference is negligible to the performance i will get with more RAM.

If you're talking about WD HDDs, the 750GB is way faster than the 500GB. I know because I got both right now :) 

I'd pay the extra $20 for the Silencer 750W. It's one of the best PSUs out there and you can reuse it for several builds.

For a HDD, I recommend a WD6400AAKS, unless you need more than 640GB for data.
