BFG GTS 250 1GB OC VS. SAPHIRE 1GB ATI 5770

PLEASE HELP ME, I'VE BEEN THROUGH 3 CARDS ALREADY RADEONS 4650, 4670, AND NOW I'M ON THE BFG ECO 9800GT STILL NOT HAPPY!
I have a Gateway DX4720-03. Right now I'm running a BFG Nvidia 1GB 9800 GT ECO. Its a 256 Bit card and it runs fairly well but I want more. The core clock on it is at 550, the shader is at 1375, and the memory clock is at 900. So its a good card but as you can see by the specs its not that fast. My problem is space. My Sata plugs are in the way, so I can't fit one of those big ass GTX260s, and up. The radeon 4870s, 4890s, and the 5800 series is to big as well. So far the only cards I have found that will fit and seem to be an improvement from my 9800gt are the (SAPHIRE 5770) and the (BFG NVIDIA GTS 250 OC). Here are specs from both cards. The GTS 250 is basically what I have now but overclocked much faster and its 256 bit. The 5770 is 128 bit but it has fast speeds as well and DDR5 memory with DX 11. I don't know the difference between the Sapphire's (800 STREAMING PROCESSOR UNITS) and the BFG 250's (128 STREAMING PROCESSORS). THE SAPPHIRE MEASURES IN UNITS AND I DON'T UNDERSTAND HOW TO EQUATE THE DIFFERENCE. Which is the better card?

I'm not questioning your intelligance, I just want to make sure because the 5770 is only 128 bit and the 250 OC is 256? Maybe you could explain a little more for me. I'm not trying to be a wise ass, I'm just a ittle un sure because going from 128bit to a 256bit is a big difference.

Like I said before I have waisted a lot of money trying to get the right card and I just want to be sure the 5770 is better. Maybe if I could see the two cards bench marked against eachother. I've had 2 ATI cards before and always had problems. I geuss I just prefer Nvidia.

it seems that you keep wanting more right? then save your money and when you have enough go straight for bigger upgrade. get bigger case, more powerful PSU and then get the best GPU available by the mean time.

i have this kind of dilemma in the past so i can understand it how is it to feel wanting more to be satisfied. it is better for you to check all the review and benchmark before making any decision on which card to get

A GTS250 is an Nvidia card. A 5770 is an ATI card. The two use completely different architecture so you can't really compare them with a single feature.

Also, a 5770 is a dx11 card meant to replace the 4870 1GB. The 4870 1GB is an equal to a GTX260 sp216. The GTX260, in turn is roughly an entire tier above the GTS250 (The GTS250 is the same card as a 9800GTX/GTX+)


4850 ~ 9800GTX/GTX+/GTS250 < 4870 ~ 5770 ~ GTX260

Notice the 1gb 250 gts is way at the bottom and the 5770 is near the middle.

5770 hands down, at this point it would be ubsurd to buy the 250 =)
