Hi all.. a little tip when picking out a pc for Flight Sim use,
a good rule to remember is that top-of-the-line video cards (ATI's X800 & Nvidia's 6800 series,in this case) are CPU-limited. I.e., a 6800 or X800 paired up with a P4 2.4 Ghz will limit you to the performance of a 5900 or 9800XT.On the other hand,an AMD Athlon XP3000, any Athlon 64,or a 3.0 +Ghz P4 are not CPU-limited,and will allow the card to run at its full speed.

L1011blonde,

That is one of the best pieces of advice that I have seen relative to the whole video card discussions in a long while.

I have the aforementioned 2.4 gig 533 fsb machine. I also have an ATI 9800XT. Even with that generation of card, the video card rips........ but the processor and fsb/ram (relative to the fs2004 demands) is the "restrictor plate" in the system. So up away from stuff that takesd the cpu power..... framerates are good. But get into the heavy AI stuff..... and it goes to heck.

best,

.................john

Yup, my CPU is my bottleneck in my system at the moment. I was no way gonna get a faster CPU than the one I got as the prices double !!

I did buy a socket 939 mobo though so in a year once prices drop I will be able to afford an FX53 or better CPU to go in it Grin

These CPU's are unlocked so I will get faster ram and clock it a bit and should have a real nice system, well for about another year anyhow lmao.

Also on the new games that are being released you will benefit more from having an X800 or Nvidia6800, especially if you wanna play high res with high anti-alias!

I beg to differ, buy a 6800GT ,considering the top end ATI cards are still about £240 and 6800's can be had for £260, I think you'd be silly not to! , run it in a p4 2.4ghz, you have a beast of a card that'll run much faster when you eventually go get that 3.8ghz p4 or 64Bit AMD Wink

wheras regardless of what you do to an ATI 9800 (Pro, XT or SE) it'll run little better with the new cpu etc.

True, it won't run to its full potential with the 2.4, but I'd bet my children it'd out perform any of the old class cards in "real use" - Benchmarks don't tell the whole story!

Games such as Doom3 and FS9 with Anti Alaising tell the real story. Wink

Having said all that, there isn't a game on the market I can't enjoy with my paltry FX5600 and good visuals, do we all want a 6800Ultra? Hell yes, I for one would love to run FS9 maxxed with FSAA @ 1600x1200, but if I'm honest, do I NEED to? no! not at all!

Posting drivel here since Jan 31st, 2002. - That long!

The CPU will limit the FPS, but the better card will still show a good improvement, especially when the difference between the cards is so great.

I cite a relative's case where he recently installed a 9800pro on his Athlon 1.2ghz machine.

He scored in the high 5000's in 3Dmark '03 with THAT cpu....... I was surprised, as was he. I'm running a similar powered card and only get just over 6000 3d marks with my overclocked 2800+

However, any time the CPU is overloaded or inadequate, you will see the effects of the shortfall, on any system.

I'm running IL-2 Forgotten Battles at the moment, and in Perfect video mode, my FPS drops like a lead balloon, which is terrible because the water rendering in perfect mode is just awesome.

I asked about this problem, and got a few replies saying that it wasn't my video card, but the CPU that was my problem, despite the fact that my CPU is benchmarking at around 3.2 P rating.

The consensus was that we all need 10ghz cpu's now...... Tongue

Mainboard: Asus P5K-Premium, CPU=Intel E6850 @ x8x450fsb 3.6ghz, RAM: 4gb PC8500 Team Dark, Video: NV8800GT, HDD: 2x1Tb Samsung F3 RAID-0 + 1Tb F3, PSU: Antec 550 Basiq, OS: Win7x64, Display: 24" WS LCD
