hey so i posted in here earlier before i got banned for having an innapropriate username of the reeferman so basically im gunna make it a lot shorter this time
iv got a geforce 7800gt and a radeon6450, im planning on running one of them for gaming, although i currently have both installed on my dual vid card mobo (no problems so far although i know they supposedly cause conflict)

anyways basically i was wondering which one would be better overall for gaming since for what i can see they are pretty close.

The 6450 is a newer card mainly used for display purposes.

That being said, the 7800GT is a 6-year old high end card.

I think they will perform about the same according to the Tom's Hardware GPU chart:

http://www.tomshardware.com/reviews/gaming-graphics-car...

Despite this though, the 7800GT only has DirectX9, while the 6450 has DirectX11 support.

Personally I would go for the 7800GT, just because I think it would be cooler.

ya i was sort of thinking that too but the thing is it has no hdmi port as it is so old and i recently got an lgtv i use for gaming through the radeon.
basically the reason im trying to decide is cuz my friend is also trying to get into gaming and he wants to buy one of the two and i kinda wanna keep the better one

Personally I would just get a newer card, maybe something chepaer like a 6670, which is usually under $100 and then sell one of the cards to your friend.

Then keep the spare one for you and your friend to have as a backup.

You could hold on to the 7850 in the above example given that it might become an antique much sooner than the 6450 and might thus increase in price to collectors because of it being several years older. Given that, it is also much more outdated and would be less compatible with newer computers as time goes on, so for the purpose of a backup card, it is easily inferior to the 6450. For example, as a DX9 card, it has inferior hardware acceleration performance to the 6450 even in Windows 7 right now. For gaming performance, they may be close, but outside of gaming, the difference is not always so small.

thanks ill prolly look into that actually. im also thinking about using crossfire if i get another radeon card could i just use a higher end card connected to my 6450?

No, a higher end card would not be able to connect to the 6450.

Even if it was possible, the 6450 would be slowing down the higher end card.

You should be fine with one of these:

Or whatever your budget is. These are cheap and will totally out-do either of your two cards.

thanks again iv got a local computer shop thats always got awesome deals on everything so i jsut have one last question. i know that radeon sorts the graphics performance like x670 is gaming and x650 is less fast but whats the difference between for example 6670 and a 5670? or a 6670 and 6770?

or even what numbers should i be looking for in the specs?

the 6450 is faster by a bit. Neither is fast enough to really be gaming cards.

I'd say minimal acceptable gaming card would be a 6570 or 5670

generally you'd want at least a 6770.

The 6570 is the same as the 5670
the 6670 is slightly better
the 6770 is a lot better than the 6670.
July 29, 2012 11:29:25 PM

The order goes like this:

1st number is the generation. For example, a 7870 is newer than a 6870, which is newer than a 5870, wich is newer than a 4870.

2nd number is it's purpose. 4-6 are entry level gaming/HTPC. 7-8 are mainstream gaming. 9 are high end cards. For example, a 7870 is more high end than a 7770, which itself is better than a 6670.

3rd number adds to the second number. Usually the number will be a 3, 5, 7, or 9. A 7870 is better than a 7850.

So 6770>6670>6570>6450.

One more thing, if you are getting a 6670 check around for deals on a 7750 (which is usually found for $100), which will blow it away in terms of gaming.

thanks a lot that makes so much sense now!!!
well saw a few 6770s on canadacomputers, but ill definitely keep my eye out for anything 7750 or 7770 :pt1cable: 
i thought id have this com running last winter but didnt get it going till a couple months ago guess thats why my video card is so old :p .
but ya price range is about 50-100 ish. what about performance differences between radeon and nvida?

generally for your price range, radeons are going to be a much better deal.

nvida don't have much in the low end.

^ nah all they have is the GT640, which is no doubt a good card, but too expensive.

the 640 is way overpriced right now, for the same money the 7750 is just leagues ahead of it. I wouldn't really recommend any nvidia card below the 560 ti right now.
July 30, 2012 12:38:58 AM

thanks again guys. jsut gotta get myself a 64 bit wondows and a new video card should be good to go

GT640 isn't worth it, it is still a very weak card. The 6450 will beat the 7800gt in some games due to shader alone. The older Geforce 5 through 7 can really struggle in certain titles due to how the gpu internally works. In single precession the whole chip had a surprising amount of computing power when fully utilized but in titles that had what Nvidia has called "diverging threads" performance went down the toilet and is why Geforce 8 came as out as quickly as it did.

Buy a better card for general gaming.

so after about a week of searching around the interweb iv found what im probably gunna be upgrading from my current build in my SIG.
i5 either 2400k or 3750k on probably an as rock extreme 4 or pro 3 and a new PSU

but anyways to get back on topi i was reading some odd things about the 7770 so i think im gunna step it up and go for a gt670 or something around that range. anyone got any bang for your buck suggestions?

August 7, 2012 2:56:01 PM

kk sweet just one last question. when i used to buld coms a few years back, GPU's didnt really have the whole fan thing going on or the 2 seperate manufacturers, so just wondering if i should be looking for a certain maker of the 670 like MSI, GB, Sapphire, whoever it is. or does it realy just all depend on price+# of fans on card?

EDIT!! so i searched a bit and found that different cars have different core speed and memory speed so i jus would like someone to confirm these are pretty much the fastest ones? dont wanna drop 500 bucks on something that isnt totally top notch thanks again :) 

theres an asus here : http://www.canadacomputers.com/product_info.php?cPath=4...
but the EVGA seems to be a bit faster : http://www.canadacomputers.com/product_info.php?cPath=4...
August 7, 2012 4:41:09 PM

I usually go with EVGA. Although both MSI and ASUS have great cooling solutions.

well im planning on buying probably a cooler master case or something and think iv decided on the extreme 4 board so you think that evga will b fine for cooling?

If you can afford the 670, then go for it; its one of the best you can buy right now.

Just make sure you get a good power supply for it.

yeah good advice dynex definitley wont make the cut haha :p .
you know if an I5 2500k or a I5 3750k would be more even with that gpu?

August 9, 2012 1:34:08 AM

The 2500K or the 3570K would go great, but if its out of pricerange, you can always opt for like an i5-2400 or a i5-3450. Its still going to be fast.
August 9, 2012 5:56:28 AM

thanks man jsut wanted to make sure i wasnt gunna make any stupid mistakes :) . im probably not building this for a couple months anyways but im not waiting for the next intel chips, and also read somwhere that this years dont have much advantage for the price difference to the old ones.
anyway thanks again :)
