Asus M3N78-VM Mother Board.

Any PCI-E graphics card will work in the PCI-E graphics slot.

Will there be any reductions in performance or should I expect "in general" full performance?

That's kind of an arbitrary question, but the MB's PCI-E 16x 2.0 capability provides the highest level of video bandwith available. Your system's overall performance capability including CPU rendering ability which is needed to process the video card's functions is certainly something to look at and consider. It's all relavant.

Thank you,

I appreciate the input. I was thinking along the same lines as your response but I just had to hear it from another person.

Again thank you,

Grekken list you entire system specs., including CPU, RAM, HDs, PSU, etc. and maybe someone can help you find the more powerful video card you want.

So I have the before mentioned MoBo, 500 Gig Hard Drive, 8 GB DDR2 1066 mhz Ram, AMD 3.1 GHZ Dual core Processor, a 500 watt power supply, 5 fans total inside my case, two 120mm and three 80mm, and Ultra X-Blaster Black ATX Mid-Tower Case with Front USB, FireWire and Audio Ports. I would like to upgrade to a XFX Radeon HD 4870 Video Card - 1024MB GDDR5, PCI Express 2.0 x16, CrossFireX Ready, (Dual Link) Dual DVI, HDTV.

I built this board with a PII 940 a couple of months ago. Currently make use of the onboad Radeon 3200 in native Crossfire with an added Radeon 3450. I have an Antec 550w modular PSU, so I have plenty of room if I wanted to add a 4870. a 4870 with the 1GB video RAM would play pretty well on my 40" Samsung 1080P. That card would make good use at higher resolutions. What monitor and PSU do you have. You should be able swap out the Radeon 4870 with the 9800GT with what you have.

Badge,

You're my hero today.

So do you already have the Radeon 4870? Anyway, it is compatible and a stout 500w PSU should power it, if you are not overclocking to extreme 12v power consumption. 8)

I haven't even touched overclocking yet. I am just considering buying the 4870 as I just built another P.C. yesterday with my good friend that had the 4870 in the build and I am really impressed with it. I don't know a lot about building systems but I am learning. I built the system we have been talking about 3 weeks ago and I should have put more research into graphics card I think now in retrospect.

Does the Asus M3N78-VM support dual video cards?
haha and could a 500W PS handle two ATI 4970's?

Hey guys, I have a Asus m3n78-vm MoBo..and I am looking for compatible graphics card with some beef to it that will greatly increase frame rate in a few games I play. Any help is appreciated

I'm not really good in computer hardware, but in software and such I am...right now I have a nVidia GeForce 9500. Its not the best card, I want a pretty good one that is compatible in the $300 range, with a few gigs of gpu memory

anyone care to help?

ATI 4xxx series
Nvidia 2XX series.

A lot of great cards are available for under $200 or so.

Oh yeah indeed, I'm looking on newegg and a few other places. I want something that will be compatible with my MoBo so I can utilize the Hybrid SLI If that is much of an performance boost. I am looking for top of the line under $300, whats your pick?

Native Crossfire will only work with a few cards. Probably the Radeon 2600 and the 3450. I have had my ASUS 780G onboard in Crossfire with a Radeon 3450. It's very weak especially for gaming. Be sure to read your MB manual for the add on cards that will work in Crossfire with your onboard video chip. The Radeon 4890 is under $300. Much of the Nvidia 2xx series also. ATI makes a 4850/4870 X2 also. I currently have a Radeon 3870 in my 780G micro.

so its not really much of a performance boost then...

I should go ahead and get the nVida GeForce 9800 GTX that will work for the hybrid sli and crossfire..its listed in the manual.

I found this on newegg http://www.newegg.com/Product/Product.aspx?Item=N82E168...

or maybe this. http://www.evga.com/products/moreInfo.asp?pn=01G-P3-115...

I'm not sure what to pick there is so many that are decent under $250. What do you think? You seem pretty computer literate.

I want at least 1gig of memory for the graphics card 2 gig would be nice.

If the 9800 supports native crossfire, you may give that a try for now. Then you would have that card available for native crosssfire in the future should you be inclined to use it. I keep my Radeon 3450 for that purpose. I recently bought two Radeon 4850's cheap. I'll use those for a time until new DX11 capable cards show up later this year. Using Windows 7 64 I'll upgrade to a DX 11 card at some point.

nice, thanks for the information

hey guys , i know that this thread is very old but , if someone sees this please tell me is a graphic card Sapphire ATI Radeon HD5550 , 2048 MB , DDR2 , 128 bit , HDMI , PCI-E would work on my M3N78-VM mother board. Basically i want to know if it supports 2GB of graphic memory....

Read the very first reply circa 'any PCIE graphics card will work..." Better to start a new thread instead of bring up a 1 1/2 year old dead thread.
