Default Sapphire Radeon HD5750 Vapor-X Crossfire

I finally got around to actually testing out the 5750s in Need For Speed Shift (with various graphics settings) rather than just enjoying playing the game.

My System:

-Processor: Core2 Quad Q6600 @ 3.57 GHz
-Memory: 8GB Mushkin Blackline PC2-8500 @ 1060 MHz
-Graphics: 2x Sapphire Radeon HD5750 Vapor-X 1GB GDDR5 in crossfire setup; fan speed set to 70%
-Display: 3x SyncMaster 2243

The cards were run @ stock settings, first:

STOCK Settings:
-GPU Clock
: 710 MHz
-Memory Clock: 1160 MHz (4640 MHz effective)

I then overclocked the cards to see if that changed anything:

Overclock #1
-GPU Clock
: 870 MHz
-Memory Clock: 1160 MHz (4640 MHz effective)

Overclock #2
-GPU Clock
: 870 MHz
-Memory Clock: 1255 MHz (5020 MHz effective)

Here are the results (FPS) as per FRAPS. I didn't log anything. Max FPS is the maximum on the FRAPS real-time display. I was only half-playing the game...and spending a fair deal of the time mowing the track-side lawn, actually...and primarily focusing on the FPS display. Average FPSs given are my impressions of where the frame rate tended to spend the most time.


1. 710x1160 (i.e. stock)

-5760x1080, 0xAA; all settings otherwise MAX: 30 FPS max (24-30 FPS avg)

When [H]ard|OCP tested a single card, they had all settings to low and the game was *just playable*, with framerates around 30FPS; their setup was i7 920 @ 3.6 GHz -- AMD Radeon HD 5750 - AMD's ATI Radeon Eyefinity Performance Review | [H]ard|OCP

2. 870x1160 (i.e. overclock #1)

-5760x1080, 0xAA; all settings otherwise MAX: 35 FPS max (33-35 FPS avg)
-5760x1080, 4xAA; all settings otherwise MAX: 27 FPS max (26-27 FPS avg)
-5760x1080, 8xAA; all settings otherwise MAX: Unplayable

-4800x900, 0xAA; all settings otherwise MAX: 48 FPS max (46-48 FPS avg)
-4800x900, 4xAA; all settings otherwise MAX: 36 FPS max (33-35 FPS avg)
-4800x900, 8xAA; all settings otherwise MAX: 32 FPS max (28 FPS avg)

-1920x1080, 0xAA; all settings otherwise MAX: 60 FPS max (60 FPS avg)
-1920x1080, 8xAA; all settings otherwise MAX: 60 FPS max (55-57 FPS avg)

3. 870x1255 (i.e. overclock #2)

-5760x1080, 0xAA; all settings otherwise MAX: 34 FPS max (30-34 FPS avg)
-5760x1080, 4xAA; all settings otherwise MAX: 27 FPS max (23-27 FPS avg)

Overclock #2 didn't add anything, so I've dialed back to the overclock #1 settings. Although the quality of the graphics was great in 1920x1080, I gladly gave up the superior graphics quality for the wider view offered in 5760x1080. 4800x900 is a nice middle ground, with lots of screen real-estate, while allowing me to run 8xAA and still get almost 30FPS.

Some people have commented about micro-stutter problems with crossifire, but I didn't run into any of that except when I kept ATI Catalyst Control Centre open on top of the game window.

I'm very happy with this setup. The Q6600 and 2xHD5750 allows me to run NFSS with Eyefinity enabled, with almost maximal settings and still get a reasonable framerate. It's not a monster setup like a 58xx and 59xx, but for my purposes it does the job and was less expensive than a single 58xx card.

There don't seem to be many user reports regarding the 5750, so I just figured I would give a bit of info about my experience so far.
