I am running an i5 at 4Ghz in Windows 7 with a good 550 watt power supply (Cooler Master) and a Nvidia 275. What sort of improvements would be shown going to a 480. Thanks,RH

Robbie, You're going to see an increase in frames, not a lot but some. More importantly, you'll see a smoother sim. You will have to upgrade your PSU though. I think 650w is the minimum recommended PSU for the 480.

I had a 275 GTX and now have a 480 GTX. Information on 480 GTX specifications with other complimentary components here:ORBX FORUM THREADComparison with other video cards on same system here:AVSIM FORUM THREAD I hope that helps.Kind regards,

Hi Stephen, Not to hijack this thread, but I'd be curious to know what your bios settings are to get your 930 to 4.3. I can get mine to 4.0 stable, but that's as far as I can get. that's with a Vcore of 1.343.

Hi Mike,Here is a thread on bios settings in ORBX which records the bios settings I use. It can run fine as high as 4.4 (210x21) on air, but I turn it down to 4.3 (206x21) since my Mushkin ram (just like yours I think) does not like to be OCed much above 1600mhz with cas 6 timings. The cooler keeps the temperatures low. I think if you up your core volts somewhat you will find safe and stable performance at those levels, but only if things remain cool.ORBX TECH FORUMSI hope this helps.Kind regards,

You should be able to run higher IQ settings also.jja

Stephen, Thanks, that's a great overclock guide.

Wow! So much for the FSX is CPU bound theory. I appreciate the responses and links. The only problem I see is that my 550 power supply is not powerful to run a 480. How about a 470? Do you think it is powerful enough to run that?RH

I think It's just enough to run the GTX 470 which I have the box says minumum 550W power supply and it's tested with an i7. But that's not really being on the safeside. Especially since your OC'd to 4Ghz, Ithink it's better to get at least 700W

I upgraded from a gtx 260 to a gtx 480 and the difference was noticeable immediately. Faster load times, scenery refreshes quicker (especially after slewing), and I believe the 1.5 gb of RAM helps with texture loading capacity. Even though FSX is mostly CPU bound, I think the video card is still important and a old one can still bottleneck an otherwise top line system.I recently have added *******'s BP=0 tweaks to my cfg, and I think that alone is supposed to move more of the FSX processing away from the CPU to the Video Card, making it less CPU hungry.I'm a happy camper!The only gripe on my system, I cannot use the ENBseries Bloom mod. It causes FSX to CTD when I switch to windowed mode :Black Eye:

+1 the 4XX are a great series of GPUs

im thinking about swapping my Quad GTX 295s for a pair of 480s in SLI, but i heard the heat might be too much?anyone run these 480s in SLI mode? -feng

If you are worried about heat go with the GTX460.  Get a dual fan model like the Gigabyte OC version.  You will save a pile of cash going the 460 route also.jja

thanks for the info. I'm getting some price quotes today for the 480s.....and also a pair of 460s to compare.-feng

Thanks guys for the responses!RH
