I am planning to buy a graphic card. I have $100-$140 budget as of today and want to play newest games (if its possible with that much budget ) I have Gigabyte GA-G41M-ES2L mobo and single module Transcend 2 GB DDR2-800/PC-6400 ram on it. I am planing to buy another 2 gb Ram so it will be 4 gb total. I have Intex 450 Watt power supply unit and i don't want to change my psu consider this. As i mentioned i have like a budget up to max $140 budget and my purpose is gaming. Please suggest me a decent gaming graphic card for that budget. Thanks in advance.
an AMD 6770 would be my recommendation.
I don't believe that the intex power supply is of very high quality. (one +12V rail at 22amps??) But i think it should be enough for the 6770, anything more I would suggest getting a better power supply.
If it indeed has a 12v rail with 22amps on it that means it has 264watts on the 12v rail. However it is of questionable quality meaning it may be rated as peak wattage instead of continuous. That means in reality you could be getting even less then that. You may be able to pull it off with a 6670, but it is cutting it pretty close, you should consider a new PSU, you can get something better for 70 bucks or so.
There are many PSU's for about $40-60 which will allow your system to run without a problem with even a hd6870.
Like this one: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
That is a 500watt corsair PSU, they are good quality (corsair makes great PSU's, the builder series is not the best but it is much better than your current one). It has 34A on the 12v rail (408 watts), and costs $49.99 after a mail-in rebate, so it is a great deal.
Another option is the OCZ ModXstream Pro 600watt psu. It costs $48.99 after a mail in rebate, and it has two 25A rails, so a total of 50A (600watts). It is SLI/Crossfire certified so it can take even two 6790's. This one has more power than the corsair one i linked above.
then you only have 20 amps on the +12v rail. That's not much and it's certainly not enough for a HD 6790. Also I don't see where you have any PCIe 6 pin connectors on that PSU. AMD says it requires two 6 pin connectors for power and minimum 500 watts PSU.
The Corsair PSU posted above by fil1p was the suggestion I was going to make. It covers all the bases and has two 6 pin PCIe power connectors.
Edit: I know it seems like a big expense but a quality PSU that at least meets the minimum requirements is a must have before a graphics card.
First of all thanks for akk your answers. It seems like better think to change my psu but i can't afford it now so ill stick with mine. One of my friend is selling his XFX HD-577A-ZNFC Radeon HD 5770 1GB 128-bit GDDR5 Video Card and i checked newegg item info it says minimum 450 w psu required so do you think my psu can handle? Other then this there are those cards i found but again i don't have any idea my psu can handle please help about this here card list i put some of card that you suggested and my friends card and some of others Please pick one of these as your suggestion so ill buy it you can tell different brand tho if you think other brand s card is better :
1-XFX HD-577A-ZNFC Radeon HD 5770 (Juniper XT) 1GB 128-bit GDDR5 (My friends) 2-XFX HD-575X-ZNFR Radeon HD 5750 1GB 128-bit GDDR 3-HIS H675F1GD Radeon HD 6750 1GB 128-bit GDDR5 4-HIS H667FN1G Radeon HD 6670 1GB 128-bit GDDR5 5-SAPPHIRE 11202-00-20G Radeon HD 7750 1GB GDDR5 6-MSI R7750-PMD1GD5/OC Radeon HD 7750 1GB GDDR5
and another question is GDDR3 or GDDR5 what is the difference and are there considerable difference between these?
I would have to agree that the hd7750 is better than the 6750, and it should use less power, so it is a win win. Also I would take the Sapphire version of it as the MSI version you posted is overclocked and will draw more power, however even if it is overclocked it still should run on your system so don't worry to much about that, as the overclocks on those cards are just slight overclocks. So get whichever one is cheaper, which I think is the Sapphire version. Sapphire makes great cards, and so does MSI, so get whichever one is cheaper.
Also as the person above me said DDR5 is a lot faster, and most modern GPU's use it, they only use DDR3 on Low end GPU's
Ok as you said ill go for 7750 however as i saw you didnt mention hd 5770 s name which is my friends card (i can buy from him for a good price). I checked your AVP benchmark hd 5770 has better fps than 7750. Does it consume more power than 7750? Can't my psu handle it? Pretending maybe thats because you didnt mentioned it??
And i found this site looks pretty neat do you think its accurate? http://extreme.outervision.com/PSUEngine
Well the 5770 consumes more power, the new 7000's series in general is very efficient, performance in certain cases will be better with the 5770, but it will draw more power, some of which you may not even have. To stay on the safe side it is probably better to get the hd7750, as it is newer, runs cooler, and draws less power. How much is your friend asking for the hd 5770?
Well the hd5770 uses about 93 watts on load, and the hd7750 uses 43 watts on load. So the hd5770 uses more than twice that. It should run on your pc but it is really cutting it close consider that you have ~260watts on the 12v rail, so 260-93=~167watts for the rest of your system to run. So that may lead to an unstable system. It is recommended to use a good 500watt PSU for the 5770, but I have seen people run it on good 450watt PSU's without a problem. The hd 7750 would be the better choice, but if you can get the hd5770 a lot cheaper it may be better, however PSU wise you may run into some problems, however guru3d tested it on their system and the total system power consumption was 321watts, however they ran on a high end i7(overclocked), so your pc will draw less power, by quite a bit. So you should be able to run a hd5770 with your psu, as their system uses a lot more power compared to yours.
Note that that the total system power consumption was with only the GPU on load, while the rest of the PC was not on load, which is why it looks good, while gaming with the CPU stressed out things could be different.
