Bottleneck question

Hello!

I've asked here before on opinions on building a new system, however I recently had a thought about maybe just upgrading my current build to extend it's life.

My current config is in my signature, but I'll list it here for easy viewing:

Intel Q9450 @ 3.2 ghz (Zalman 9700 cooler, I can push this OC more if needed)
4gb (2x2gb) OCZ Platinum DDR3 @ 1600mhz
EVGA 790i Ultra SLi
PC Power and Cooling Silencer 750 watt
EVGA GTX 285
OCZ Vertex Limited Edition 100 gb SSD (Win 7)
2x Seagate Barracudas (1 has Vista, other is storage)
LG 21.6" Monitor, 1680x1050

I'm looking to upgrade my GPU to possibly two 460's in SLi. I'm not too sure if I would be bottlenecked by my CPU or my RAM. My motherboard supports 2 16x PCI-Express lanes, so PCI-E bandwidth is definitely not an issue.

Question is then: If I get two 460's in SLI (thinking the 768mb models, 1gb might be overkill for my resolution even though I like to turn on eye candy), what would be my most limiting bottleneck, if any?

I thought Intel's quad aren't the best for gaming?
Really there won't be an issue...

^^That is not true.

I don't think that you would face any issues since you have already overclocked it to 3.2GHz.

I'd go for it. That is what that m/b was made for.
High CPU speed : check
Large cpu cache: check
DDR3 memory : check
SLI M/B : check
PSU covered : check

Bottlenecking is an over used term around here. The truth is, almost every system is bottlednecked from time to time depending on the game.

However, given the resolution you game at, I doubt you'll experience much real improvement (FPS over 60 are usually not seen due to monitor limitations), unless you play a lot of DX11 games. What kind of FPS do you get now and with what games?

the bottleneck would really depend on the actual game itself. As is your OC Q9450 will do fine with the GTX 460 in SLI.
in this article of building a balanced PC, you can see a stock Q9550 is actually bottle necked by a GTX 285. With a GTX 295, you can see a small OC CPU would balance the CPU and GPU very well. if you played at a lower res, the CPU becomes more of an issue but at 1680x1050 you are fine. if fact at 1200p you would running neck and neck with an i7 if both of used an ATI 5970.

that being said, the GTX 285 is still an excellent card for 1680x1050. Just because you can upgrade does not mean you should. I would skip the GTX4XXX series and wait for the GTX5xxx (lets hope Nvidia does not rename the GTX 460 as the GTX 560)

VERY interesting CT.

I'll have to ponder then.

I'm typically playing Grid, L4D2, WoW, but I'll be playing the new Medal of Honor and I still play Crysis from time to time. I just hope that I don't have to wait too long for the 5xxx series.
