260 GTX SLI or new CPU?

I'm currently running an E6750 (at standard 2.67ghz) with 4gb ddr2 800mhz on an Asus P5ND and a BFG GTX 260 (factory OC, 590mhz core).

I'm thinking about getting a MSI GTX 260 (T2D896, factory OC to 620mhz I believe) and trying to run it in SLI with the BFG.

Problem is, I'm wondering if it's going to be bottlenecked by the CPU, and if I'd be better off upgrading it to an E8500 before going to SLI.

Also, will my 650W PSU be enough? Most people seem to suggest 700-800W, but there seem to be plenty of examples on the internet of people running 260 SLI on as low as 500-550W.

Thanks in advance!

At this point in time I would suggest waiting a few weeks to see whether the GTX560 turns up as one or two of them would be a much better bet.

You would be bottlenecked by your processor. Also, don't get an E8500. The value of it is SO much less than that of the Q8400.

Twice the cores, 30 dollars cheaper. All you're missing is 2MB of cache, which is more than made up for in the cores.
The GTX 260 is an old card, anyway. You would be better off getting a single, more recent card than going SLI. If you go SLI anyway, your 650w PSU will support them. I'm running 2 HD4870 1GB cards off of mine. No problems at all.

Only if the app or game uses more than two cores, if it doesn't then you'll be suffering a performance loss due to the slower clockspeed and reduced cache.

Thanks for the reply. I was planning on going SLI just because it's so much cheaper than getting a new card (I can get a 260 for about $80, second hand), yet according to the charts on here, in SLI it gets almost the same framerate as a GTX 480 in Bad Company 2 (the only game I play that I have any framerate issues with at the moment).

Looking at CPUs now, and I'm leaning towards the Q8400 just because it's cheaper (minimizing cost is a big concern for me), and Bad Company 2 actually supports the extra cores... any thoughts?

New CPU ?, Intel SB would be my recommendation
new GPU ? GTX 560 or HD 6950, depending on how long u can wait


Uh, dude... I just said minimizing cost is a big concern... if I had the cash to completely overhaul my system then this thread wouldn't even exist.

I would overclock that CPU and get hold of a GTX 560, which should release in a week or two.

just get 260s in sli,if you donot care about directx11.it will be best to suit your needs.

It's just that ur system is not worth upgrading yet, IMO


Ah, ok. Yeah I'm starting to agree. I might get the second 260 while I can just because it's so cheap, but I'm thinking it doesn't make much sense to drop money on a new cpu for a dead-end socket.

thats right gtx 260sli will still max out many games with good settings,just go that.

I envy you. Overclock the CPU to around 3.4-3.5 Ghz if you can . After a few days of researching the forums i found out that the E6750 has the best performance for the voltage and power consumption around that speed. I run mine at 3.4 Ghz. Ou, and Q8400 is not such a great CPU. It has a low speed and small cache. If you want to go quad buy from the 9000 series(q9400 up).

Wish i had 2 gtx260..he he.

Done! In fact, overclocking the CPU to 3.4 has taken care of my framerate problems, without spending any money (at least for now)! I guess the CPU was already bottlenecking the vidcard, so getting another would've just been a waste of money.

Thanks all!
