Heya,
runs really well, but not as great as I would have expected. The p5wdh has a lotta problems, most of them arise if you want to overclock tho (check this: xtremesystems.org/forums/showthread.php?t=110193) . Hopefully Asus will fix them soon with further bios releases. And for some reason my ram appears as PC4300 instead of PC6400...I'm still looking into fixing it. Unless you like the unique features on the p5wdh, like the ezraid and the nice expansion slot layout, I would say go for a p5bdh deluxe, its a lot more stable and cheaper. And they are a lot easier to get, the p5w's seem to be out of stock all the time. This is my full spec:
Lian-li v1100B Plus II Chasis
Core 2 Duo E6600
Asus P5W DH Deluxe
2gb (2 x 1gb) OCZ PC6400 Platinum Ram
MSI NVidia 256mb (VT2D256E-HD)
Sound blaster X-fi platinum
Ultra x-finity 500w psu
Thermalright Ultra 120 CPU Heatsink
74 gb Raptor
320gb seagate
2 x 500gb seagates in Raid 0
Nec 4570a dvd-rw
benq 1655 dvd-rw
Mitsumi floppy + card reader combo (forgot the model #)
But anyways, regarding dscaler, I'll give it a try and post how it turns out soon. Thanks
