2 New GTX470's or 1 GTX470 and a new Processor?
 
Here's what I got: Asus PND32SLI deluxe, E8400 Core 2 Duo, 4 gigs Corsair Ram, Corsair 750w PSU, 2 8800GT's in SLI, all in an Antec P160 case along with a DVD burner and two SATA2 HD's.

Now, a GTX470 is about the same price as a new Q9650 processor. Do I go with one new GTX470 and upgrade my processor, then get the other GTX470 in 3-4 months, or do I get both cards now and wait another year or two to do a full MB/processor upgrade to LGA1366??? If I go with the two new cards, is my processor gonna bottleneck me significantly??? Harumph!!! I think my PSU will be ok, I only have a DVD drive and two SATA HD's in my Antec P160 case.

Any help here guys?

From what I have seen so far regarding SLI testing of 470's, you do NOT want to go that route.

If you really want a dual GPU system, stick with ATI for now.


Otherwise a single GTX 470 would an excellent upgrade. Though dropping $300-$350 on a Quad Core, to be brutally honest, for gaming and general use, isn't likely to net you an enormous performance improvement.

Check out our chart's for a comparison between the two: PCMark Vantage x64 CPU Benchmarks - HardwareCanucks Charts

I think you're missing something here, I have an SLI board, not crossfire, and actually the few GTX470 SLI reviews out there say that the SLI scaling is fabulous. Couple that with the reports of new owners that the cards are actually alot cooler and quieter in real world systems than was initially thought, the GTX470 SLI, for me, is very attractive. My issue is not ATI vs. Nvidia here, it's whether my CPU will bottleneck me.

I had a look at the CPU charts, and ran through the benchmarks quickly Gaming performance between the two CPU's is 15-25% better with the quad core. I think that is significant. If I couple that with a single GTX470, I might be looking at a 50% performance boost over my current system. But you're right is it worth the extra $350? ARGGGHHHH!!! I hate these decisions!!! :biggrin:

2 x 470 SLi will be fine PROVIDED you're OC'ing your E8400 to at least 3.8 Ghz...4 - 4.1 Ghz would be better...any less that 3.8 Ghz will "choke" your 470 SLi config....if your not OC'ing your E8400 SLi 470's would be a complete waste of $$$, another factor of course is what Res you run.

Exactly my concern. I have a hard time OC'ing my current CPU, it gets wiggy about 3.4-3.5. So I'm leaning towards just getting the one new card and replacing my processor to get another couple years out of my current 775 setup. I can always get a second card down the road if it looks like the quad core will overclock well for me. Does this make sense?

I currently have a Benq 24" and run at 1920 x 1200.

With two 90C gpus and an ancient nvidia chipset I don't think its a good idea either. + overclocked CPU = massive heat issue. Specially with your current case, it seems to only have 2 fans.

Just settle for one or a gtx 480.

Sure, and Ncix just happens to show the PNY GTX480 in stock....bugger!!!! :doh:

Upgrade the CPU, motherboard, RAM, and get one GTX 470 instead of two. You do NOT want two GTX 470 together unless you don't mind going deaf.

He already had 8800GT's in SLI, I would think he is past that point.

Production sample cards are far nicer to temps. I havn't been able to push a GTX 480 over 85C yet.
