Hard to say if it'll be significant or not -- WoW performance isn't typically used as a benchmark. It's also highly dependent on your graphics setting (resolution, whether or not AA/AF is turned and with what settings, and so on and so forth). In some games like Call of Duty going from a 8800 GTS to a 260 will literally double your frame rate in some situations. In other games/settings the speed up is more like 20 - 30%.
Probably not enough to be worth it yet. The WoW was more of a "holy shit" sort of thing since I was used to 60fps with the settings all to full. Keep in mind this is also the low end 320mb version of the 8800 -- from the charts it looks like the 512 is significantly faster.
If you can read this, you're on a board populated by misogynist assholes.
Ah if the Core 7 has been out that long I guess the price reductions have already kicked in.
Here's what I'm going for. (Canadian dollars)
Intel Core 2 Duo E8500 $239.99 Asus P5QL Pro $124.99 OCZ 4GB memory $69.99 Sapphire HD 4850 512mb $204.99 Coolermaster 650W P/S $89.99 Antec 300 case $84.99 Windows Home Pre 64bit $144.99 Seagate 500GB sata 32mb $69.99 LG DVD-RW $34.99 Assembly Fee $35.00
TOTAL : $1099.91
The odd thing is that the identical system from NCIX (Canada's attempt at Newegg) would have cost me more. This system is about 50 dollars less than their online quote and I don't have to deal with delivery fees or annoying mail in rebates. I guess the local computer store I got the quote from figured I'd be shopping around so they gave me a decent price without having to be haggled with.
