Posted this first on the FSX forum but was adviced to post it here.I am having a computer built because the ready made one from HP did not met the specifications recommended for FSXGot estimates from two diferent shops.From the first shop I haveVista Home Premium.

I've seen posts like this by you all over the place... aerosoft, avsim, and everyone has given you an answer by now. What more do you want??????

Just get the cheaper one of the two, they will be identical in performance. If I were you I would perhaps try to get some sort of "extended support" thrown in FOR FREE from either shop, just tell the salesman that where you purchase depends on this and then stand your ground until they agree.It does not matter what manufacturer sells you the GTX275, they are all essentially the same. Just get the cheapest one.You are buying the right system for FSX with heavy addon use, that is for sure. No chance of wasting the 1600 euros so chill 'n enjoy! :( And do please read NickN's guides for both FSX and systems set up here BEFORE you install anything, the OS inlcuded. Your enjoyment of FSX and the fantastic graphics it offers will depend directly on your ability to follow these guides to the letter. Deviate at your own risk.Konrad

To me the i7 is no answer to FSX and its coding mysteries...... A simple dual will run it just fine if configured correctly...

Are these just as good or better than I previously mentioned.Only trouble it is Vista 32 bitsIntel Core 2 Duo E8600 2x3,33GHz 6MB BoxCoolermaster Hyper 212 S775/754/939/949 4GB DDR2 A-DATA+ Series 4-4-4-12 (2x2GB) 2 x 750 GB Samsung SATAII 32MB 7200rpmPalit GeForce GTX275 896MB DDR3 PCI-E Coolermaster Centurion 5 Midi TowerCoolermaster Silent Pro 700W PSU Christiaan

Not sure what you mean by configured correctly? Does this mean overclocked to 3.8GHz or more? And if so where is the simple (for the average user) in that? I also happen to know from previous posts that the OP has a lot of addons he wants to use with FSX and in this scenario recommending a dual core is not a good idea in my opinion.

Configured correctly means simply set up properly installed.Defragged...Control panel set up properly..FSX sliders set to what the system can handle...I said nothing about OCing to 3.8..FSX will run fine on an OC of 3.4..I run a E5200 OCed to 3.4 and it runs everything I toss its way at med to high settings...Thats with FEX..GEX..UTX.. On a 3850 vid card stock..That is also with no OS tweaks or FSX config tweaks..I lock frames at 35 and they hold there all day..Just did an experiment with FSX and all sliders maxed for the most part..Out of KSEA in Building Storms..22-28 on the ground and 33-35 in the air just after take off...I could have applied a TBM tweak but it was not really necessary..I do however not fly with those maxed settings...I find that FSX behaves very well on a dual core .... And on my 3850 card looks beautiful...

harleyman:there's no way you're pulling off those numbers at true "near maxed out settings" because I get only about 17fps on the ground at KSEA in bad weather with minimal traffic (10 percent) and there's no way your system is more capable than mine.
