like many other people review this video card , I buy it to upgrade my old Dell 2400 with its original Celeron CPU run at 2.08 ghz . install it be a bit strange because I do not install the driver first . I just install the card and boot up , expect a alert about the driver . the alert never come , possibly because my dsl modem be still on-line . it be a goofball move on my part , but maybe people would like to know that NVidia pretty much cover all the basis in this regard . so , to answer the most important question ; YES THIS NVidia CARD work perfectly with my OLD DELL DIMENSION 2400 with the orig Celeron chip still install . -lrb- read on about my CPU upgrade . -rrb- # 1 once the NVidia be through install its driver , then negotiate with my new ASUS ml228h 22-inch Ultra-Slim Widescreen LED Monitor , I notice the follow ; \*\*\* jaw-dropping clarity , resolution and speed . -lrb- speed mean a improve frame-rate at YouTube , Hulu , and the few video and movie I have in my download folder . -rrb- YouTube come up to about 20fp , Hulu about 25fp with my old CPU still install . -lrb- not too shabby for my old fossil Dell . -rrb- \*\*\* seamless integration with my system and recently add 2gb of new Cosair RAM . -lrb- yes , the Dell 2400 REALLY doe accept 2gb of ram . -lrb- 1gb per slot . buy faster mem chip than you need in case you upgrade you CPU as I decide to do . -rrb- I buy this ; Corsair memory vs2gbkit400c3 2 gb pc3200 400mhz 184-pin DDR Desktop memory kit \*\*\* seamless integration with my new Pentium 4 CPU run at 3.06 ghz . -lrb- I highly recommend this CPU for all Dell 2400 owner as it be one of the only two option originally offer by Dell . -lrb- I buy - Intel TRAY PENTIUM 4 3.06ghz-ht 512k 533fsb s478 -lrb- rk80532pe083512 -rrb- it install very easily and boot up flawlessly right from the start . it be be perfect ever since . -lrb- even though it be list as `` used work like new . '' -rrb- this new chip lift my frame-rate to 24fp for film project , and a full 30fp for standard video at both Hulu and YouTube - something I think impossible for my Dell no matter how I upgrade it . -lrb- yay ! no more video hiccup and drop frame ! -rrb- # 2 after the installation of the new CPU , I only see a bit of a improvement in frame rate etc. , but eventually I have to shut down for one thing or another , and when I boot up again , the first time I get on-line I notice some activity that worry I a bit . shortly after , I realize that the Invidia card be still on `` auto Update , '' and have already install a update driver and whatever else it seem to think I need . ordinarily this would have upset I a bit , but when I see the incredible improvement , I bite my lip and simply enjoy myself . it be only after that automatic update that I see the framerate lift to 24 and 30 for film and video -lrb- respectively . -rrb- # 3 if you have a slow old Dell like mine , I insist that you sell you sister , you car and maybe even you toilet to get a few buck together and make the improvement I do . the RAM , and CPU be not that expensive , and even the LED Flatscreen I buy be only $ 140 here at Amazon -lrb- what a incredible monitor . -rrb- those three addition together , pull I away from even consider a whole new machine . I be go to be happy for 3 to 5 year at least ! -lrb- although I must admit that I be not a game-player , so play the latest game at full speed be not important to I . -rrb- I apologize for the lengthy review , but it take I quite a while to discover all this stuff , and I figure that anybody interested in this NVidia card have get a old machine with pcus slot and not the newer pci-express slot . for I , NVidea aim this product straight at the older machine `` target market , '' and in my opinion , they hit the bulls-eye . I could not possibly be any happier with this product . and with all the other change , there be not anything my system do that do not happen in a blink of the eye ! boot up be faster , my desktop icon flash across the screen in a instant , and even my hard-drive activity have increase in speed . for those who be interested , in all my search , I discover that the single most important change I make be the p4 CPU chip . in several forum , I find the the l2 cache it feature , -lrb- 512 kb , -rrb- be much more powerful than what the Celeron chip have . this cache deal with core instruction set and since it do this work right on the chip , the large size of the cache have a huge and immediate effect on the overall performance of the machine . I prove this out for myself , which be why I let myself buy a USED CPU chip . -lrb- my thinking be , that a use CPU , might possibly have fewer hour on it than my old Celeron chip . -rrb- besides , these p4 be become more and more rare each day . -lrb- get yours now ! -rrb- I would recommend the Sparkle GeForce 8400g to anybody with a older machine with standard pcus slot . if it add a burden to my puny Power-Supply , I do not seem to notice it so far . -lrb- Registered temperature be still well within acceptable spec . -rrb- the provide driver and include software seem to deal with all the expect problem one might expect with such a powerful upgrade . -lrb- a damned miracle IMO . -rrb- I highly suggest the other upgrade too , but make sure you do you homework . verify what I have discover , and follow any and all tip when it come to installation . -lrb- like fresh new thermal-paste if you upgrade you CPU . -rrb- happy holiday !
