I had considered this in the chipset subform, but I wasn't entirely sure, so I figured this would also work. Feel free to yell at me if it does in fact belong in that sub-dwelling. It could actually go in 'homebuilt systems' too, really, but I digress.
I have recently purchased a whole buncha parts for my new computer build, mostly everything except a few things I already had lying round. I'll give you a brief run-down for reference sake ..
- Q6600 processor (planning on overclocking)
- XFX 4890 XXX video card
- HAF 932 case
- Thermalright Ultra 120 HSF
- 4 GB Patriot Viper Extreme Performance DDR2-800 + 4 GB OCZ DDR2-800 (mixing RAM, lovely hardware lottery)
- Corsair TX850 PSU
- Asus Xonar DX 7.1 sound card
- Sunbeam Rheobus fan controller
- OCZ XTC RAM cooler
- P5Q pro motherboard
- LG 24" (1920x1200 res)
Now, the issue at hand is the P45 chipset on the P5Q pro. Although a lovely, stable chipset, it has the unfortunate quality of only running 8x/8x in Crossfire mode. Unfortunately for me, I was also planning on adding another 4890 card in about a month or so. However, the single card will of course run at full 16x.
The X48 boards, on the other hand, run with full 16x/16x bandwith in crossfire, and therefore won't 'bottleneck' high-end cards, to speak. If you refer to the tweaktown reviews/benchmarks ( http://www.tweaktown.com/articles/1472/intel_p45_vs_x48_crossfire_performance/index7.html ), you'll see a significant difference between the two chipsets. Now, that particular benchmark is Crysis, only one game, but demonstrates the performance difference in a pretty stressful environment.
Other benchmarks comparisons available at http://www.legionhardware.com/document.php?id=761&p=2 however, demonstrate smaller performance drops with the P45 chipset. Although, it should be noted that that particular benchmark is Crysis in DX9/no AA, so less demanding than the previous benchmark.
This is mostly an advice question: should I consider returning my P5Q pro (order hasn't arrived, yet) in favor of an Asus Rampage Formula X48 board, assuming I go Crossfire (2 4890s)?
Here's a link to the X48 board: http://www.ncix.com/products/?sku=29239&vpn=RAMPAGE%20FORMULA&manufacture=ASUS
And a link to the P45 board (already purchased, can return): http://www.ncix.com/products/index.php?sku=30418&vpn=P5Q%20Pro&manufacture=ASUS
Mind you, the X48 board is also twice the sticker price of a P5Q pro, but considering the cost of 2 video cards for Crossfire and the P45 performance concerns, I'm thinking I should consider it.
Does anyone have any personal experience with P45 chipsets vs X48 chipsets with Crossfire?
Any advice is appreciated.
