The Intel chipset is slightly faster than the 680 chipset in synthetic tests, however as you have an 8800 i would go with the P5N32-E SLI if you want to SLI it in future as the intel only supports crossfire
680 boards have 6 sata connectors, 985 boards have 4
I got a P5N32-E SLI, as it supports quad core and has 3 PCIEx16 slots and supports 1333MHz FSB so for me its as uture proof as you can currently get
the only difference i can see with the striker is that the striker has LED's
I wasnt aware the P5N32-E SLI was a hybrid like the Plus as the sticker says 680i and none of the reviews i read reported it as a hybrid

This difference of speed can be noticed while playing games or no?
very very very doubtful, ive only seen difference of mabye .5%( http://www.tomshardware.com/2006/12/19/intel_or_nvidia/... ) which would equate to around a quarter of a frame per second, youd probablty get that back by closing down something like winamp before running a game. Due to that I wouldnt base which board to get on game performance, theyre relatively the same, the only real divverence that matters to the consumer is if you want a crossfire board or an sli board and how many sata poarts you need, the intel boards are also slightly cheaper than say a P5N32-E SLI
Nvidia's nForce 680i SLI is the best chipset for Core 2 Duo or Core 2 Quad systems, but only for real enthusiasts and hardcore gamers
Others can save a lot of money by going after a more economic Intel P965 solution, unless you're interested in state-of the art features.
Our recommendation is simple: Go with the nForce 680i SLI if you want the best platform for Core 2, or stick to the P965 if price/performance is your priority.
P5N32-E or P5N32-E Plus?
These two board are totally different, although, the Plus version reports to be a better overclocker, there are some other people that got good results with the non-plus version too.
Also keep in mind the Plus is really a 650i SLI chipset with a 570 SLI SB. The nonplus is a 680i with a 590 SLI SB
Reports have said that the P5N32-E Plus runs too hot when very overclocked, i cant confirm/deny this with the P5N32-E SLI as i had to RMA mine and im waitign for the replacement. Also i did some digging around, the P5N32-E SLI does indeed use the 590SLI as does the Asus Striker extreme
The northbridge and southbridge remained unchanged, the 680i SLi SPP (C55XE) and the 590 MCP (MCP55) are used here as well.
The difference between Asus P5N32-E SLI and Asus Striker Extreme are both analysed here - http://sg.vr-zone.com/?i=4528&s=4
Their conclusion seems that the P5N32-E SLI is only missing the bling bling of the components. For performance
Unsurprisingly the P5N32-E SLi performs identically to its more expensive partner in most of the tests.
For overclocking they said both boards are identical apart from price
