Hello,I had just purchased my new Pc as following:Intel Core2Duo E8800 3.00 MhznDvida 9800GT 1GB , with GigaByte chipsetGigabyte MotherBoard4GB DDR2Westen Digital 500GB HarddiskGigaByte Case with 5 Internal Fans550W PowerSupplyCan i run FSX efficiently with Addons like REX and ASRegards,,,

YupAl

The only problem is am running now FS9 and getting 30-50 fps ,but still having some sort of lagging and unstable pictures flow on the screen P.S: I had the last Driver UpdateRegards,,

Let me put it this way: I have a Hewlett Packard Pavilion DV entertainment laptop, which has no fancy graphics card at all in it and just 2 Gigs of RAM built in with a Core 2 processor at a slower speed than yours. It runs Vista 32 Bit version, and the only thing I've done to it is updated the graphics drivers and stuck an SD Card in the side slot which is configured as extra memory. I can run FSX on that thing perfectly well and in fact it is the machine that I test products on when reviewing them on Vista, since my main desktop PC runs XP.That's a far less impressive spec than your PC, so if yours cannot run FSX, then there is definitely something amiss.Al

Thank you for your helpI was just considered since iam getting 95% performance on FS9 with some laggingP.S: When i updated the nDvida Driver ,it told me the Driver needs more power . So I have to extend a wire from PowerSupply for additional Electricity . Is that relevant to the performance ? Regards,,,

Your motherboard and probably your graphics card too, will likely have a manual that will be the best source of advice on what power take offs from the motherboard or PSU are necessary (the manuals are usually an A5 paperback, but if you don't have them there are invariably PDF versions available as downloads from the maker's website). It very often is relevant to how well they perform, and if it is a necessity for your graphics card, then you should have the cable required to do so which came with it, unless it needs a take off from the PSU, in which case there will likely be one going spare which you can utilise.You do sometimes find that lesser power supply units can struggle to deliver the necessary gusto to the motherboard for computers with a decent graphics card that draws a lot of power, and if you overtax a PSU with too much demand, it will definitely be the weak link in a system and is likely to have a short life.Whenever I build a computer, I always put a heavy duty PSU in there, since I learned over the years that although they do consume more electricity, they will keep on going where a lesser PSU will simply cook itself to destruction trying to keep up with what it needs to output. A stable power supply to the graphics card is fairly essential to avoid the graphics card glitching and skipping out frames and should not be overlooked; it is simply a false economy to get anything less than what is up to the job, which is a painful and expensive lesson I learned from building a few PCs over the years LOLThe other bonus with a big power supply unit is that you can cheerfully add extra cards to the motherboard and not worry about taxing its capabilities, since a heavy duty PSU will not only have the guts to kick out the power, but will also be likely to have enough power take off leads to make it physically possible too.Careful when doing all that stuff by the way, unplug the power lead and Earth yourself to discharge static before commencing any sort of connecting malarkey in your PC's case. Try to touch things as little as possible - always on the insulated parts and not the metal contacts - as there is a risk of discharging static into sensitive compnents which can cause damage in rare cases. Mess with the PSU too much when it is plugged in and you can be rewarded with an electric shock too (even when it is not powered up), so unplug it and touch things as little as you possibly can, and always on the insulated parts. If in doubt, ask someone with more knowledge to assist you, as mistakes can be expensive and very occasionally dangerous too. Reading the manuals for the motherboard and graphics card may be tedious, but it is usually worth it.Al
