Hi. I'd like to ask about upgrade for my pc..

I currently have Q6600 oc to 3.0
MObo: evga 650i ultra (non-sli)
gpu: evga gtx 260 216
PSU: corsair 650w

i'm gaming at 22" 1680 x 1050 monitor

I'd like to come up with a good decision because i'm planning to buy an upgrade this coming black friday and then continue this christmas.

I'd like to ask if I would go for ati, then I would buy a MSI x48 (found 1 for $99) http://www.tigerdirect.com/applications/SearchTools/ite...

then go with a 5850 or 5870 then cf it when prices come down. but will there be any bottlenecks if I would go for 5850/5870? if non, going for cf, will there be bottleneck?

If I would go for Nvidia, I would buy this p7n http://www.tigerdirect.com/applications/SearchTools/ite.... then wait for gt300. but will using gt300 card result in any bottleneck using a q6600?

I'm really worried about bottlenecks in both configurations. thanks in advance...

I would stick with the MSI x48 board, since Nvidia chipsets pretty much suck on the LGA775 sockets.

At a resolution of 1680x1050, you would be better suited going with a 5850 over 5870. The 5850 will max pretty much any current game at that resolution. If you don't upgrade your monitor, I don't see the need for you to Crossfire. If you do Crossfire 5850's, your Q6600 will start to be a bottleneck for pushing both cards. Neither will be a concern at your resolution. You'll be running over 60 FPS maxed no problem... IMO.

Also, an upgrade to your PSU might be required for a Crossfire setup. The 650TX only has 2 PCI-e connectors and you'll need four. I would recommend upgrading to Corsair TX750W 750-Watt Power Supply - ATX, 140mm Fan, SLI-Ready, SATA-Ready, 80Plus, if you have plans on Crossfiring down the road.

what about going with x48 then with 5870 then going cf with it? what is the requirement of 5870? can the tx650w handle single 5870? will my rig handle 5870? no bottlenecks?

what is the requirement of 2 5850s cf? is 5850 good enough for a few years?? 2-3ish?

You can do that, if you want. At your resolution, I would save myself some money and just get the 5850, which will max out games.

The 650TX will handle one 5850 or 5870 with no problem. You will run into issues with it, if you plan to crossfire, which is why I said look at the 750TX.

Your rig will handle the 5870 or 5850 without a bottleneck. At your resolution, you aren't stressing the CPU or GPU enough to cause any type of bottleneck.

To CF 5850's, U still would recommend the 750TX. CF 5850's will last 2-3 years depending on the games you play and if you can live with some of the "eye candy" turned down on your games.

If you purchase only one card, I would go with the 5870, which will last you a year or two depending on games played. At the time games max your 5870, you can add another one for additional power and upgrade your PSU to handle two cards.

if i would upgrade my psu, going cf with either 5870 or 5850, is there a bottleneck on the q6600?

No... Gaming at 1680x1050 will not stress the Q6600 out enough where it bottlenecks the CF setup. If you were to start playing at 1920x1080 or higher, then I would say it will bottleneck the CF setup.

Another thought for you... Have you thought about upgrading your CPU instead of getting two GPU's? This will decrease your risk of a bottleneck and help increase performance. I would highly recommend the Q9550 over the Q6600. Here is a comparison so you can see the difference. Q6600 versus Q9550

buying another cpu i think is useless because if i were to upgrade it and cost aroun 100+, then i would just upgrade to i7. but i think that would be for my next build. I just want to finish this old pc (having it future proof for games) then just set it aside then build a new one.
October 29, 2009 1:59:01 AM

i saw your post. but i think those were stock clocks. i would oc my q6600 to about 3.0-3.4. it would be passed the stock clock of q9550, so the fps should be above or the same as your post displayed.

you think going with x48 then cf 5850/5870 would be enough to conclude this build? also, gaming at 1680x1050, would the 5870 be an overkill? or is the 5850 enough for future proofing my rig?

1.7 wood screws and pcb cut outs, erm.. ill just say that

Hey, don't know if you noticed this or not but that msi x48 board only allows for 4gb of ddr2.

CPU bottlenecking occurs with lower resolutions... GPU bottlenecks occur with higher resolutions. at 1920x1080 or higher, you will have less of a chance for CPU bottlenecking.

if you can wait , at least have a look at gt300 before you commit your dough .
October 29, 2009 7:35:19 PM

guess i'll just wait for the gt300 to come out before i'll make some move. I'll go with hdd upgrade for this black friday. What is the best configuration? is there a significant boost if ssd is used for boot and os? if so, how many gb is enough? I plan to use 1 tb on storage. is it advisable to configure 2 x 1tb on raid for storage? or is it not necessary since it's just for files and stuff?

use one ssd for os , and installed games or apps . keeps the installers ,media like music/movies etc in your hdd . you do not need raid for watching movies or music or anything else . but the os and game loading etc , used most frequently , will fly in the ssd .

one question folks, Corsair TX750W has 4 x 8-pins PCI Express connectors, but both 5850 CF and 5870 CF requires each four 6-pins connectors.

the 8-pins connector could never fit the to the cards connector... could someone explains this to me

The 8-pin connectors are setup as 6+2-pin, which in this case you would just connect the 6-pin part of the 8-pin connector.

yes , and by the way 4x(6+2) pin is really handy .
