Not sure what direction to take here

My current setup:

M2N-SLI Standard Motherboard
Athlon 64 x2 3000+ (stock 3.0Ghz)
6GB (2 x 2GB, 2 x 1GB) DDR2 Corsair XMS2
Sapphire Radeon 4870
24" & 19" Monitors. Main screen at 1900x1080.
Windows Vista Home Premium 32-Bit
650W Antec True Power Trio PSU

History:
I just upgraded from a dead 22" LCD to the 24" and noticed a dramatic drop in framerates after moving up from 1650 to 1900 resolution. So I upgraded from an 8800GT to the 4870. This restored some, but not all, of the framerates I had before which suggests to me a CPU bottleneck. The CPU runs at about 65% during gaming sessions currently both pre and post GPU and Monitor upgrade.

Goals:
I am a heavy MMO (Warhammer Online atm) player and occasional FPS or RTS player. Framerate stuck at about 50 in open areas drops into the 30s in crowded areas and teens in heaving RVR fighting. I'd like to get that framerate up as high as the card and monitor combination will allow.

Options:
1. 9850 Phenom Quad-Core - Officially support by Asus with a simple BIOS upgrade Likely does not require a OS reinstall or purchase of new OS. Approximately $140

2. Phenom II 720 Triple Core/940 Quad Core - Not officially supported by Asus however reports of similar M2N-SLI Deluxe models making it work. Some indicated need for an OS reinstall. This option leaves open another upgrade path to AM3 and DDR3 in the future. Unsure of whether or not this would require a new Vista license (Mine is OEM). Approximately $170-$210, but could be higher if OS issues arise.

3. Core I-7, DDR3, Core i7 compatible MoBo - I can reuse the Video card, hard disks, CD drives so this would be looking at about $600-700 in upgrades for a top of the line processor.

Analysis:
From a price-performance perspective, I just don't know if options 1 and 2 don't give me enough extra horsepower to reduce the CPU bottleneck (*IF* that even exists). 3 certainly yields the most performance and gives me a high quality platform for a another few years, but will it really solve my current goal?

Thoughts?

Er...i'd go with #2(PII-720) to where you could get an AM3 and DDR3 later if you wanted. Plus is it price comparable to the option 1 and far less than what overall you'd spend going to the i7 920 build (about $200-350 extra depending on mobo and memory).

The 720 OCed should keep up with that 4870 alright. is that a 512MB or 1GB model?

It's the 512MB model.

Now, option #2 is nice and I meant to comment that it leaves an upgrade path to AM3 and DDR3 open.

The problem is, I don't know if I will be able to get it working. I hate to buy a CPU only to have it not work. Then it forces my hand to AM3 and DDR3 which then I might as well do Core i7. You know, since it will require a new OS license and all that jazz.

Moot question now. I went ahead and ordered:
Intel Corporation Intel® Boxed Core® i7 Processor 920
Corsair Memory XMS 6GB DDR3-1333 (PC-10666) CL9 DIMM Memory Kit (Three 2GB Asus Computer International P6T X58 1366 ATX Motherboard
Western Digital Caviar Black 1TB 7,200RPM Serial ATA-300 Hard Drive

Good luck to you, dude. Nothing wrong with the i7. Solid processor.

I went with the AMD 720BE AM3 processor and got a Biostar TA790GX 128M mobo last week. I have it on 4 cores basically at 3.4GHz right now idle 25C/load 46C right now.

What kinda cooler ya got? Make sure u get a good, solid cooler (air or water, whatever you have/can get for your money) and keep that i7 cool and it should do you right, especially running the ATI video cards.

You know, I might just grab another 4870 while I'm at it :)
