First off, don't get to hung up on the Windows Experience Rating it really doesn't give you much help. Secondly, the figures you have for the GPU seem about right for an on-board graphics solution.
Yeah, I know it's just an index, but over time I've been able to correlate a good bit of "what to expect" performance-wise into certain ranges.
And, please note I did use a question mark in my Subject. I wasn't sure whether this was low/med/high for this particular board. I guess I kinda figured that given the 512mb dedicated, it might've been a tad higher. But what I was really after was whether this was as good as I should expect with this board.
The thing to consider is what do you want from your PC? If it is working fine and doing all of the things that you want it to do is there any point in throwing money at it? Or, do you just want some BIG figures to give you bragging rights with your mates?
Well, the latter is always fun, sure. But it's not the main point, by any means. I have worked extensively on machines that scored 4.6/4.7 on the Graphics index, and definitely found their performance to be lacking (especially with multi-monitor setups). Windows don't glide along as they're dragged, videos hiccup, and so on. I'd certainly like to avoid that kind of thing with this new box, and just thought I'd give the mobo a fair shake before plunking down even more money on another card.
Adding a dedicated Graphic Card would improve your WE score but, will you actually gain anything from this except a hole in your pocket where the money used to be? If you do add a GPU you would actually do better to disable the On-board Graphics as the WE rating is based on the lowest score and, even if you put it in crossfire, that score won't improve.
I saw in a later post that you added one in, and it brought you up over 7. Did you feel the difference with "everyday" activities?
I really don't know much about Crossfire. I guess it seems like "a gamer thing"? So I don't know where I'd get the most bang for the buck. Whether to look for (this will be a purchase of opportunity if/when it happens) a totally standalone card, or one that works in conjunction with the main board.
To be sure, it's not about the score as much as it is the experience. I'm a value shopper all the way.
